Those who were around in the 1960s will remember the furor caused when this machine came to market. I dedicate this article to my late father Chris whom had one.
The Akai M8 was not the best machine out there, neither was it supposed to be at the price point it was released. It certainly wasn’t cheap but more to the point, those that had the test tape will remember that it’s fame was not around the tape quality at 15 i.p.s. but rather 1 7/8 i.p.s. and the Cross Field Head, licenced by Tandberg. Many audio enthusiasts unfairly compare this machine to professional machines at the time which came out with three motors. The point here is that a machine with one motor is often more difficult to design compared to one with three motors. These motors can be very expensive and in order to mass produce at an affordable price point there was usually quite a bit of sophisticated engineering involved. (a case in point is that many enthusiasts in the 50s and 60s used to design and build their own mechanisms – often with three motors. Solenoid and switch control is easier to design (and build) than manufacturing cams, linkages and gears).
The M8 has made its appearance again over the last 5 years, not for it’s marvellous deck but for it’s audio amplifiers. I recently purchased one and will be restoring the deck and the audio section. A good price is usually around 100 dollars for a working unit. I paid about 65 dollars for mine. I do not know whether the amplifiers work because I should run them up through a variac first (which I don’t have) but the deck does need some maintenance. Strangely enough the pinch roller is not in bad nick although the belts will need replacing. This unit must have been kept in storage for some time gauging by a look at the casing.
Wow and flutter, hum and noise and cross talk may not have been perfect but I do recall on the new machine recordings of piano playing were usually exceptional – I recall this because I was ten at the time. When my hearing was still intact. A ten year old doesn’t know what wow and flutter may mean but will certainly complain if it was audible. The other thing, at 15 ips these machines were very capable. Most RTR of the time were only 3 3/4 ips and looked their age. The M8 in comparison looked like a space ship. No, it’s not a Zoom H6 but in capable hands and with good quality tape some pretty damn near professional recordings could be had.
This deck will be restored because I do believe the transport mechanism is not in bad shape (which we will come to later). Quite often on the forums we have the vintage collectors pleading for owners not to cannibalise or modify these decks for the amplifiers but personally speaking if the deck is in bad shape it may just not have any value to the owner in any event. Many of the students of tube technology have absolutely no interest in the deck – only the sound of the amplifier. My recollection is that the amplifier quality was not bad, a fairly flat response and the reproduction of vinyl was crisp. This was also in the 70s when transistorised amplifiers were making their mark. Not knowing much about audio quality I do recall the solid state amplifiers as being powerful and crystal clear, the tube amplifiers were just lost in all that power and “perfect” imaging of the program source.
I do not believe that tube amplifiers are better than SS. I do believe that they sound different and depending on their use tubes can be superior. I do not believe that tubes should be used for home theater and in my own experience if one needs a tube microphone preamplifier it should be all tube. Power amplifiers are cheaper in SS format and we shouldn’t be clipping them in any event unless that’s the desired sound required. Tubes are remarkably resilient and for those that now claim they have a lifespan of two years then I wonder how CRT manufacturers got away with for so many years. My personal favourite is Mullard. Tube biasing is a personal cringe I have. We have so many different types of biasing now available today one must wonder if the engineers of yesteryear were just plain stupid. No, it’s all marketing hype. I have worked on transmitters delivering thousands of Watts to the load and the only advantage we have in modern times is that the critical safety circuits have all gone the SS route. Because it’s cheaper and more compact.
The EL84 output stage of the M8 is nothing unique. The design was very popular and of course the EL84 was definitely one of our more popular tubes. In the USA we have other permutations and audio engineers had their own preferences, often very valid. Compare USA and Brit guitar amplifiers for instance. The more popular “Hi-Fi amp” was the push pull version of the EL84 amplifier. In the 70s I rarely came across any tube amplifier reproducing more than 15W and the El34 was seen as an extravagance – quasi-complimentary and complementary transistorised amplifiers were becoming popular, didn’t smell as much and were way more efficient. I mention “smell” here because anyone not familiar with tube equipment will think there’s something wrong when first powering up their vintage piece of equipment.
Something to remember:
Tube amplifiers use in most cases dangerous voltages on their anodes (or plates) and screen grids. The supply rails can be anything above 250V DC and in high powers 750V or more. This will cause serious burns and God forbid, your early demise if you are not careful. Ensure the equipment is switched off and unplugged. Discharge all smoothing capacitors either across their terminals (better) or across ground and + rail. Do not use your multimeter probe to short out the capacitors if you value the probe. Tube circuits use high impedance and it’s not advisable to “probe” around on the control grid circuits unless your meter has a very high input impedance.
This Akai deck is often compared to decks costing very much more. Indeed the M8 does not have a boastful spec compared to modern equipment but then again neither does Tandberg, Teac and Revox/Studer. The Akai GX series were funky looking and the quality on spec often superior to the older tube amplifiers and single motor decks. They can be obtained off eBay for fairly realistic prices. Magnetic material (composites) used on tape for recording and the biasing also plays a remarkable role in the end product.
Interesting article here: The Roberts Akai relationship at the museum of magnetic sound recording. (we include this because there has been a large amount of nonsense written about these two brands in the forums).
The triple B factfinder’s column – Bullshit Breakfast Club
Google has unwittingly inspired many armchair wannabes to become experts in most fields, specifically dominating the IT, mechanical and electrical engineering industries but having its origins we believe in politics.
The ability to write well, stick a bun on the back of your head and behave with an air of confidence is fast becoming the norm, a frightening thought if one understands the phenomena known as the Dunning-Kruger Effect. Society has become full of it, possibly driven by the relatively new lack of standards in the IT industry. Now we smell the fresh aroma of cow dung at every gathering, party or pub visit.
Bullshit Anon – The fresh smell of manure in the air
On a recent visit to Orlando I had to chuckle to myself when I overheard an aviation expert persuading his many listeners in the smoker’s lounge that the reason why smoking on aircraft had been banned was because the authorities had calculated that over 200 kg of tar had accumulated in the passenger cabin of a 727 after only one year in service. The mind boggles.
Has one noticed that oft a geeky, pimply youth would wrap a nerd-like set of specs around his scrawny head, create or attach the bun hairstyle, drop the trousers to the knees plumber style and transform into a potential Bill Gates. Or the guy with a multi-meter becomes a Carver or Voltaire. In recent times I have come across real mechanic donning a clean pair of jeans and golf shirt but the dodgy around the corner auto expert puts on a dirty pair of overalls. It’s all perception folks.
My GP come medical practitioner come doctor does not wear a white coat and stethoscope, some of the best IT boffins look normal and yes, because you wear a suit doesn’t make you an honest individual fighting for the cause. A friend of mine whom holds two degrees, one in electrical engineering and one in computer science tells me when he is stumped. He is also very intelligent. The typical anti BBB candidate.
Is the reason for Donald Trump’s many recent successes because he is anti BS. He is certainly not politically correct, indeed possibly even blatantly sexist. I’d love to see an unbiased listing of the demographics of his voters. I think we may be surprised. But yes, maybe this is what we need – someone who calls a spade a spade. I personally don’t like bullshitters. Even more, people that don’t even know they are bullshitters. I don’t want to walk into a shop which only sells high end audio gear thinking that the more I spend the better it’s going to be. I want auto manufacturers to build a car without frills so when I buy it second hand five years later I can fix it without breaking the bank. I want to buy anything based on the transparency of the sale. I want to see a website showing all the flaws in products. I do not want some geeky, pimply dude with a bun hairstyle telling me this is how it is.
Can you imagine a politician becoming a salesman? The bad news is that good sales people are as close to dammit as politicians. From Wiki: “Politics (from Greek: πολιτικός politikos, definition “of, for, or relating to citizens”) is the process of making uniform decisions applying to all members of a group. It also involves the use of power by one person to affect the behavior of another person.” Note that there is no reference to “the advancement or betterment” of “another person”.
I like musicians. They understand politics because many of them write about it. They do more than politicians to serve the poor. Musicians practice what they preach (mostly) and have very little tolerance for bullshit. Tracy Chapman, Roger Waters, Stevie Wonder, George Harrison, John Lennon, Ed Kowalczyk, etc – 99% of them. Real musicians. Often politically incorrect but mostly not suffering from the Dunning-Kruger Syndrome. You will never become famous if you are not good. A musician cannot tell you how good they are until – they have to prove how good they are.
An international airlines pilot is a rated professional. They have regular tests to check competence. Whether all the tests are relevant is immaterial. We have to learn to trust this individual or individuals. In most industries this is not the case. A Bsc graduate in auto engineering may be totally incompetent in his field whilst the highly competent artisan is sidelined. This happens very often – Bullshit Baffles Brains.
In years to come we will reflect on the old artisans, long since pensioned off and deceased whom did what they said they could. We live in an age where the voice of authority is expert. Every single car manufacturer out there vies to have the best technology available whilst the roads collapse, where drivers cannot drive and there are no trains or buses. We live in an age where we sell curved TV, have 8K cameras and where the cheap Atom processor outperforms high end processors of ten years back. We have millions of computer languages, compilers and translators. We have multistandard TV systems, mains voltages of 100, 110, 120, 220, 240V. We can read up on this and more.
But that doesn’t make us a real chef, real technician, real mechanic, real artisan or trusted doctor, attorney or accountant. And that’s what makes Steve Jobs, Bill Gates, Voltaire, Marconi, Flemming, Sinclair, Ford, Wright Brothers, Prince, Jackson, Benson, Bono, Madiba, Rooseveld, Churchill, Bosch, Stanley, Livingstone different. Because they did it.
Actions speak louder than words.
Einstein said: “Two things are infinite: the universe and human stupidity; and I’m not sure about the universe”.
(Ed’s note: Eduan was forced to write this article after an office braggart told everyone how he had changed the idling speed of his car to make the engine run slower to get a higher top speed. Also the same guy with a not seen helicopter license and “designer-engineer” part time for a manufacturer. What we do know is that has made two girls pregnant in the office and is employed as a “marketer”).
Let’s face it, we all dream about it but know it can’t happen – a self driving car! Yet, this is on the cards. Mercedes, Kia, Toyota, Ford, Audio, BMW, Volvo, you name it, they all have a car which can drive autonomously. “Not on our roads though” say the authorities.
It wasn’t that long ago that our great-grandfather was told never to drive faster than 100 m.p.h. because the blood would leave his body. In those days 40 m.p.h. was classified as breathtaking. Now we have Andy Green in his ThrustSSC breaking the sound barrier. He might have been white as a sheet when he cruised to a halt but his blood flow was normal and his body parts were still intact. Of course we digress but isn’t this what science is about – proving it wrong!
Autonomous or rather automated vehicles which require external and environmental assistance through usually magnetic strips and road navigation transponders is not something new, in fact was on the drawing board in the early 1980s. However, with smaller, faster and more reliable computers, highly sophisticated sensor systems and state of the art electro-mechanical output devices we have come to a cross-roads – cars which are driven near autonomously and when to mass manufacture? Only time can tell although major manufacturers already talk about the latter part of this decade, some as near as 2017. Unfortunately all of this will come to a nought, we believe, because of the road traffic authorities. Actually more so, the fraternity of global electronic engineers all shake their heads in disapproval. The thing is, we can fly an aircraft totally unmanned only because there are critical backup and redundant systems in place, not many obstacles to bump into and even less corners to negotiate. Motor cars are on land, they rely on absolutely accurate input data at all times and last but not least, the critical thinking aspect to this entire exercise, no errors or hardware failure. And this is where we have a problem. Imagine driving merrily along at 70 m.p.h when a sensor fails, the radar decides to stop working or the computer decides to reboot (unlikely but who knows). The global think tank may be right.
Control freaks will never let go of the steering wheel. They are also some of the world’s worst drivers. Every year hundreds of thousands of people, pedestrians, drivers, occupants, (animals too) are killed on our roads. Traffic authorities have all but given up. What percentage is caused by driver failure?
Partially automated vehicles already protect the occupants of a vehicle when crossing lanes inadvertently, applying brakes when needed, stabilising a vehicle which may be on the verge of rollover and preventing unnecessary skidding. So why can’t they be made to drive the occupants to a destination without driver intervention? Because it cannot. It’s called the unknowns. What happens if?
Interesting to note that driverless cars use the cloud but flight MH370 didn’t. Losing communication to the driverless car may make it pull over to the side of the road and stop. What happens if the side of the road happens to be a cliff, dropping 300m to the sea or a rocky outcrop? No thanks. Although the same electronic engineers designing the workings of your trusty four wheeled carriage will swear to the reliability, they are the first to banish the notion of driverless cars. Quite rightly.
Autonomous Cars – if the roads allow it
Just as one was told that you may drive safely but not necessarily the “other” driver so it just so happens to be the reason why driverless cars may be on the drawing board and even successfully tested, it’s the “other” car that remains the problem. Just because the roads in Sweden and Germany are better than most third world countries makes the very idea of driving the Yungas without a steering wheel a frightening thought.
But no, as a matter of fact we do believe that driverless cars are here to stay. We do believe that if the road is not safe the driverless car will stop and tell you that you are on your own. If a machine which has proven to have more powerful thought processes than the driver’s brain pulls over because it is not safe then believe me, you are not safe.
Many years ago most drivers took to the roads because of the pleasure of it. Nowadays it’s a case of whether you will make it back alive. We cannot blame the authorities neither can we blame the electronic, automotive and mechanical engineers. Unfortunately scientists and engineers alike know that we can no longer rely on the human element, there has to come a stage where there is forced intervention. We can only blame ourselves. The authorities and engineers shouldn’t put a ban on it but embrace it.
Isn’t it frustrating to shop for the ultimate sound system on a limited budget. You see one, you hear one and that one on the next rung up always sounds that little bit better. Fortunately we have good news. It’s all in the mind.
Anyone being an avid reader of any electronics and audio magazine that does comparison tests will often get overwhelmed by the amount of products on sale, let alone by the costs of these high end pieces of equipment. It’s almost like playing chess against a grand master – no matter the move, there is always one better. So it is with audio gear. The problem is, we often fall foul of the marketing machine and sales personnel pressure. Don’t. Whatever you do, never buy a sound system based on whatever someone else tells you. What we do know is that power output is no longer directly linked to pricing, semiconductors are cheap. Even Chinese manufactured toroidals are no longer the price it was ten years back. But what should one know?
Inputs and more inputs, all with the same output
Most audio amplifiers brought out over the last few years have surprisingly good build and sonic quality. For movies one loves the idea of being able to set up the sound stage through a microphone and an automatic process. However, audio installers complain about most users not setting up their systems properly even with electronic assistance Read up on this in the manual. If you are only buying the integrated amplifier like most of us do then ensure you have sufficient inputs. This seems to be the most important thing in the designs found currently on the market – millions of inputs. On a practical level these inputs should be HDMI and one or two for legacy use.
Marketing trends push for big power and in our experience this is true, go rather for overkill. Pick up the amplifier, weigh it if necessary. Most of the weight is transformer and cooling based. A Class D amplifier is light – that’s a design advantage. Class AB will be heavy – that is also a design advantage. If it’s Class AB, delivers upwards of 60W x 5 or 7 channels it will be heavy. How heavy is heavy? We have our own estimations but do look at manufacturers such as Marantz and NAD. These guys don’t skimp on components least of all quality of the mains transformer. The importance of this is multi-fold. Read up on how tests are done and in this case, specifically output power measurement. Transformer secondary (output) voltages sag when under load. Power supply regulation is critical and to compete with the best there should be no compromise. This is where most budget systems cut costs.
Purchasing an amplifier which lacks oomph will cost more in the long run – you will be disappointed. If it’s a headphone amplifier you want then one needn’t be looking at killing your ears in one sitting. And no, you cannot put audio amplifiers in series to get more power. What you can do is purchase separate pre-amplifiers/processors and power amplifiers. It will work out cheaper in the long run if you need to upgrade for higher power. This a more expensive solution but possibly a better long term plan. A well looked after, carefully selected preamplifier/processor may even prove to be a lifetime “investment”.
Six channels or more, two is best
Two, three, four, five, six, seven or ten channels? Here the choice is yours. There are many audiophiles passionate about their movies but only use two channels or stereo. The home movie expert may prefer the most amount of channels he can afford. 5.1 is still rated about the most common. Quantity over quality? A good quality stereo setup beats a multi-channel movie theater setup for music anytime. (of course this is bias).
Tubes versus semiconductor? Dollar for dollar there is absolutely no equaling the transistor or semiconductor. (I will add this though – my own opinion is that early transistorised amplifiers lacked the musicality of tube amplifiers. If transistor amplifiers were first on the market maybe I would have rewritten this and in all likelihood battled to justify the rationale. The fact remains though, musicians on a whole tend to prefer tube sound. So there!).
Why on the edge? The objective of any audio amplifier is to faithfully reproduce the input signal as an exact image except for amplitude at its output. Through the years scientists and engineers have near perfected this art. A bench tested audio amplifier which reproduces with clinical precision the input program material to its output will sound good through a quality loudspeaker system. Most amplifiers today, except for cost cutting in the power supply will do exactly that. So where to now?
Digital is Doomed
Although we are living in the digital age man and machine will never be the same. Our logic is often irrational and therefore biased. We cannot live in peace with each other because of this exact reason. With audio equipment we take a very sophisticated (in scientific terms) analogue signal, convert to binary, we then read the binary and convert to analogue. We them chop the analogue at a high frequency, modulate with a sawtooth wave, switch at a high voltage and finally filter out the high frequency component. We then feed the analogous high amplitude signal to a transducer which is an analogous device. Then the marketers come along and tell us vinyl is back!
We have fine tuned the Class D amplifier for home use but yet it’s true advantage is when used in cellular technology. We have lowered the cost of high powered audio amplifiers through this technology but yet loudspeakers have always been the obvious weakness, both in cost and efficiency.
It is time for manufacturers to look at cheaper and more efficient methods to reproduce this amplified signal. The fixed magnet, moving coil paper or synthetic cone speaker *aka dynamic driver) should be cast to the ash heap, audio amplifiers have been re-looked at so many times that it’s run out of steam.
Although there is no doubt that cars with high safety standards are a feather in the manufacturer’s cap it can also be said that many argue about the reliability of some of these cars and indeed, gauging by the number of comments posted by readers on some of the safety reviews, whether statistics are biased or somewhat ambiguous.
We don’t believe that these stats are wholly skewed though as cars with a higher safety spec, often the German marque, do reflect a lower incidence of drivers and passengers succumbing to injuries in the event of an accident. The argument is often more about the vehicle size than safety. The argument is based on smaller cars causing more injuries. Our argument is that it is very seldom the car but always the driver – cars don’t cause accidents, drivers do. Guns don’t shoot people – people do. A driver is not legally entitled to drive a vehicle which is not roadworthy, neither under the influence of narcotics or alcohol.
Safest Cars Vs Safest Drivers
Not wearing a seatbelt is considered illegal in most countries and provinces. A question arising here is whether seatbelts and airbags are interlinked. Of course they are. This question comes up quite often and here we have another dilemma – why aren’t learner drivers taught this at driving school? Any person taking to the road for the first time should have been taught about the differences between AWD, FWD and RWD vehicles, stability and traction control, ABS, wet weather driving, gravel roads, speed, under and over steer, overtaking and HP versus torque. Not just where the pedals, horn and indicators are located. We know that talking and texting over a cell phone is not a legally entertained practice but what about eating and drinking in a moving car? We need to get this right first and then can talk about what can happen in the event of an accident.
Motor cars are dangerous beasts and the faster one drives the less chance occupants of a vehicle will get out alive in the event of an accident. Which accidents are worse, head on collisions, side or T-boning, rear-ending, overturning or landing in the drink? Most accidents can be avoided by taking the defensive driving approach which then of course includes driving within the speed limit and thinking ahead. Ever notice how some drivers speed up when it rains? Often AWD vehicle drivers are the worst transgressors. And small pickups (empty) with very little traction on the rear wheels.
Driving the Driver
According to the more technical, modern motor cars are driving the driver – the driver becomes reckless knowing that his car can pull him out of a tight spot. This is a dangerous take on any situation. Motor cars all have a safety margin of safety and a head on collision at 100 mph is not one of them. Braking hard at 100 mph may be fine in a Mercedes AMG but not in a 1995 Ford Escort. Driving under a truck with both vehicles will not leave much behind even at 50 mph. NCAP ratings don’t necessarily expect one to drive under a truck.
The safest cars on the road today are often the most unreliable. Well this is a view from many armchair critics and gauging by the amount of negative publicity that certain cars have produced it’s an easy conclusion to come to but truth be told we don’t know how often the car gets serviced, how it is driven and neither the condition of the roads. What we do know is that if one specific car can get 300 000 miles and another of the same type only 20 000 then we need to look at the driver and of course, the old theory about Monday cars. The fact is that modern cars are more reliable than older cars.
Feeling safe with AIDS
Stability control is a proven life saver for countless amount of drivers in SUVs but we’d rather know that the driver is aware of the risks of driving a high center of gravity vehicle at speed rather than him or her relying on an aid. Because that is what it is, an aid. An airbag may save your life but it is useless without a safety belt. Which brings us to the last point: driver safety.
Cars do not lose control, drivers do. Stick to the speed limit, don’t drive intoxicated or suffering from fatigue, adhere to the road traffic signs, keep off dangerous roads, slow down in the rain, ensure that your car is roadworthy and yes, checked by the AA once per year, play by the rules, be courteous, be watchful and alert and then you may be surprised to find that NCAP doesn’t really mean much at all.
The world’s safest cars are only as safe as the driver.
“We often miss opportunity because it’s dressed in overalls and looks like work” – TA Edison
Loading the latest piece of freeware that looks like AutoCAD but isn’t I was enthralled by the complexity, the genius of the software engineers and the ease of use. Much, much later I realised with dismay that we had friends coming around for dinner. Why is it we always friends around for dinner when I am testing out new software? Interestingly enough I am not a design engineer but this software had me enthralled. One month later it still had me wrapped around it’s finger of bits and bytes.
In that month I could have built a bird cage, rebuilt my old Ford engine, gone to the movies, reconnected with old friends and even re-landscaped my garden. I didn’t though because I was stuck behind the screen, as my brother calls it, in “Crouching Tiger, Hidden Dragon” mode. Computers are interesting that way, they make us damned lazy. Unless you are using your computer to make money like many do most of us are captivated by the ease of use, games and other novelties. We use it to “Google” and “Wiki”, we use it to paint, draw and write. We use it to communicate and write blogs, post pictures and troll. All of this at a price.
A computer is a very useful tool in the right hands. It was designed for the user to capture and manipulate data, it was designed to be a tool. Now we have become the tool. We communicate less effectively, we no longer write and we certainly don’t feel the urge to do something constructively once we sit down to jot our memoirs on Facebook. In short we have become freakin’ lazy. Instead of using time at work constructively, as one is paid to do, we What’sApp friends and family. We “Google” for easy fixes – as if the page will jump out and fix the kettle. There are three things a person needs to know about your common and garden kettle – it has an on/off switch, it heats water and it will make a noise when the water boils or switch off automatically. How many people “Google” for a rapid fire response when their kettle fails. I do! Most probably so do you.
I recently watched a technical video on how to strip and repair an automatic gearbox. I learnt a lot and now when we talk gearboxes I can with absolute authority maintain my own in any conversation. How many people out there are like that? Those same people have never wielded a spanner nor know the difference between metric and imperial. If ever there is an industry which has been most hard hit by the internet it must be the IT industry. There are now so many computer technicians floating around I wonder often whom is growing the beans? With a few key-strokes and a click of a button we find out which university degrees are hardest to get, read up a little and then become experts.
A few years back I needed some forms to be printed. The lady doing the job dropped the completed forms off and told me with a voice of authority that I need to check my grammar in future. I felt my stomach drop through my butt. She used spell and grammatical usage with what Word had decided and used that instead. One thousand forms written in Computer English. How many times does one read of the word “loose” being used instead of “lose” and the other favourite, “witch”. Writing a blog now has become rather simple nowadays because most people reading the content will only read one paragraph. I do this with emails, skip over most of the content and think I have enough information to generate an accurate reply.
One wonders how much the use of a computer, the switching on of a TV receiver or the playing of games on a tablet has lead to diabetes and heart disease? We sit behind a computer these days and do things. That’s what I do. Each and every day. I thought I was the only one until I looked across the sales floor.
I envy those that fix automatic gearboxes and landscape gardens.

Manufacture – the art of production without slavery
History, if left unchecked has a nasty habit of repeating itself. In the case of Africa this may very well be good news. From our young schooling days we learnt about slavery, the bad guys and the good guys. Depending on which side of the river you sit the bad guys may very well have been good guys. Liberators are the bad guys that become the good guys. In essence if there is one thing that history has taught us is that we cannot get on with our brethren. If there is one thing that evolution has taught us is that we all came from the same seed. We are taught that Africa has very little history but yet common sense tells us that it can’t be so, Africa is the cradle of mankind. Searching through hundreds of pages on the subject, comprising of white papers and reports, some from highly reputed sources such as KPMG and leading intellectuals, the one that caught my eye was that called Africa before Slavery.
One senses that Egypt has always been at war. Although we single out Singapore as being an 8th Wonder in how the nation rebuilt itself under the leadership of Lee Kuan Yew, Egypt has been remarkably resilient, under the control of the British Empire, through WW2, The Six Day and Yom Kippur Wars Egypt has re-invented itself. It is now in the top five African countries showing a strong economical growth and having the most powerful military. Strategically speaking it could very well see itself as being the strongest nation in Africa over the next few years. Will this happen though? Stability and controlling the sea route through the Suez Canal are key drivers.
2. The Republic of South Africa
The Republic of South Africa, previously the strongest of all the African nations economically as well as national defence is fast seeing itself being reduced to junk status, poor governance and high levels of corruption being major causes. The legacy of the apartheid system, current racial tension, militant workers and poor educational levels does not bode well for this country but it’s not all doom and gloom. Natural resources, raw minerals, strong financial sector, an under valued currency and the importance of the east-west trade routes remain critical i it’s survival.
Nigeria is currently the strongest economical component of the African Union. Joining OPEC in the early 1970s did little to grow the nation, then being military run. After two successive wars between 1967 and 1970 left the country under military rule and it was not until 1999 that the country had a new leader, a new democracy. By 1999 revenues were largely just an indicator of what could become, the return never given back to the nationals to improve housing, education or local business which has left Nigeria with a staggering nominal GDP for an emerging country but an impoverished society. This is changing however.
Democracy and great manufacture are not good bedfellows
Why are these three countries so fundamentally important to Africa as a whole? They aren’t because there’s a host of others but these three are the top players in their field right now, financially and in the state of manufacture (albeit low). Iran hosts some of the top engineers in the world, let alone Africa. If all states of Africa had to have financial discipline, possibly on par with that of the RSA and to be safe as Botswana then we are all in for an interesting ride. Unfortunately cultures, beliefs, greed and corruption get in our way. Democracies are never what we think they are and liberators often end up being jailers.
Skills shortage. Much emphasis was placed on Zimbabweans to get a proper education, thanks to current president Robert Mugabe, a former teacher. In many African regions there is a shortage of broadband and internet facilities, let alone PCs and laptops. Distance learning is of great importance to school goers and university entrants. On a theoretical level this applies to artisans as well. On any level the hands on approach is the most beneficial to get results quickly. Africa lends itself perfectly to the manufacturing of electrical goods, which also implies armature winding, switch gear, conductors, insulators and consumer goods. What about tools? Why do the Germans manufacture the best tools in the world? Africa can too.
Textiles. South Africa was a formidable textile producing country. Unions destroyed this through their militant behaviour. The production of affordable clothing is always a good entry into the world market.
The motor industry. South Africa remains a very large motor manufacturer. Most roads in Africa are conducive to modified two wheelers, designed to be used on difficult terrain. Yet Africa falls short in this area and India has the upper-hand. Kenya may change this with Honda investment.
Africa at War
When driving through the roads of many African countries one gets the feeling of overwhelming hopelessness yet the human spirit endures. People are friendly but are dirt poor. Yet opportunities exist, many more opportunities than in Europe and the USA. Africa is new but it is also very old. Western powers are tired of giving hand-outs. A beggar will never work if he or she doesn’t have to. Western powers are quick to hand out guns and ammunition and never get tired of this. Yet small boys and girls become killers. One doesn’t have to be a genius to understand the desperate need to prohibit the use of landmines world wide, not just in Africa. There are numerous resources on this horrific practice. Are there winners after a war? There are many articles written about the influence of the Cold War on Africa – South Africa was not the only one.
Egypt was King
Although Africa has never been known to be a great manufacturer of goods one needs to look at the influences of Islam and Egypt going back centuries. Africa needs to distance itself of the political influences of the west (and east) and go it alone. War in Africa has never been a solution, only a catalyst of destruction. Right now China is brokering deals with African nations to foster partnering in projects. There is no such thing as a free lunch, in this case, a “free road or bridge”.
Educate, Upskill, Build
(Author’s note: One needs to live and work in any country to understand the cultures of the people. Afro Americans do not share the same cultures of the peoples of Nigeria, neither Afro Europeans of Tanzania. If one is white and born in Africa this does not make one a Euro African or Euro South African. I am South African. There are Khoisans living in London whom are British).
Reliability statistics – a dodgy dump of grievance
About ten years ago my sister-in-law phoned her husband frantically telling him that her engine had just fallen out of her Renault Modus. It was a protection cowling. She now drives a Spark.
Wiki: Reliability in statistics and psychometrics is the overall consistency of a measure. A measure is said to have a high reliability if it produces similar results under consistent conditions.
Plugging up your service plan
It wasn’t all that long ago that cars ran forever and you only needed to change the plugs, condenser and points for a full service. Now we have a major problem on our hands: cars are unreliable according to statistics and you need to be a millionaire to own an entry level car. Ummm, not quite.
Cars are much more reliable these days. Engine design, materials and lubricants have improved many times over. Your old 2.5l Chev motor may have put our 90HP, modern day engines put out 300 or more HP for the same capacity. And they last longer. But the truth is out….
It’s all in the driver.
Drivers don’t have a maintenance plan!
Find out which cars are owned by whom? Would a 20 year old settle for a 2001 Toyota Corolla when he can get an Audi A4 for the same price and it’s a 2005 model. Would a 60 year old fisherman settle for a Q7 or a HiLux pickup? A Honda Civic is a sensible car. It’s known for high mileage, cheap to service and fairly fast. Sell it to a 20 year old, it gets chipped, after market parts and an impressive set of wheels. Suddenly it becomes unreliable. Are we looking for longevity or something that never breaks down? A Formula One is reliable but is not known for longevity even when it’s just parked.
Reliability sells but it won’t catch you a cheerleader.
Repair prices and vehicle failure statistics can make or break a sale. Toyota sells off the used car floor faster than a porn star takes off her underwear. Likewise Honda, Subaru, Golfs and Polos. German cars of the luxury variety are getting some serious media attention these days and it’s not good news. They are just plain unreliable. But here’s the thing, are these stats taken in the USA or Germany? The Germans are pioneers in precision. Don’t say their technology is too advanced. They were sending rockets into space when the rest of the world were trying to figure out why our blood doesn’t leave us at over 100 m.p.h.
A wolf in a sheep’s negligee
Statistics cannot be reliable when one doesn’t know that Joe Blog uses his Mazda RX 7 as a jet ski, that Auntie Sue drove her Galaxy to church only, at 80 m.p.h. in first gear and Uncle Percy could get up the Himalayas in his Vauxhall which was towed by a Land Rover.
What If – my car has a tow hitch in the front?
Each vehicle brand carries the culture of the manufacturer. The manufacturer homeland 0ften carries a semblance of the culture of the country. And so it goes. Putting this another way, experience showed me that the Panasonic TV (CRT) was the most reliable TV of all time. Phillips made wonderfully easy to repair TV sets. Sony made really great to view TV sets but once out of warranty could be a bastard to fix. What we do also know is that in many of these brands the failure was usually caused by Electrolytic and Tantalum capacitors. This then caused other parts to blow, usually semiconductors. Picture this now in an automobile where stresses are much higher and of course, the temperature. Picture the crises we face when hybrid cooling systems fail because we get water in the transmission fluid. Cars parts must be more durable. In an aircraft there is absolutely no room for error. If NASA designed a TV set or car it would run for ever or at least it should. What’s the message here? Stress and heat kills. And here we have the “what if” scenario.
What if a manufacturer took the bull by the horns, went back to the drawing board and laid out a plan which took all possibilities into account which may reduce unreliability many times over. We would have a perfect car. But here’s the thing though – they try to. That’s why we have R&D and crash testing. The bigger problem here is how fast do they want a new product on the market to stay in competition (and some cynics ask whether they want their cars to be all that reliable). A common complaint is that Toyota stick to the tried and trusted formula, their style is conservative and it reflects in their cars. Good for them. “What if” is important. That is why Boeing and Airbus stick their necks out and make sure if something can happen it won’t. But it does.
The best advertisement on earth.
Toyota also take great pride in their product and do ensure that the owner gets the best bang for his or her buck for every little part used in their vehicles. So what if the door clangs, at least it doesn’t fall off. Remember that Top Gear series which had a HiLux as the unintended star of the show. After trying to destroy the vehicle through hitting trees, drowning in sea water, dumping a caravan on top of it and then cruelly sending it to planet earth in a building demolish this HiLux made it through, not unscathed of course but still running and moving under it’s own power. Off the top of your head what do you think this meant for HiLux sales. And the Arctic expedition?
Maybe other manufacturer’s should be letting Jeremy do the same with their products. Then again maybe that would not be a good idea. Me, I am a Volvo guy. I fell in love with the 144 and every product thereafter. I’d love to see a Volvo falling off a building on it’s roof. And then driving off. Toyota appeals to me but their high end models are very expensive. Because they are so good at what they do Toyota gets good resale value on all their products, sometimes more than what one paid for it. Anybody for a Conquest?
Marriages made in hell.
What happened to the great Chrysler-Mercedes wedding? Ford and Volvo? It’s no hidden secret that Ford wanted the Volvo roof to use less steel because there was no proof that it saved lives. Ouch! Ask breakdown truck owners whether this is true or not? Or the authorities. It’s also true that Chrysler and Mercedes do not share the same company culture, employee culture, country culture. Geely and Volvo? The outcome here is going to be interesting. From my armchair I predict that for the first time ever Volvo is going to be giving the German’s the shakes like the South Koreans and their Japanese competitors and yes, even VW. Volvo needed a cash boost. I would have loved Volvo to go to Tata but Geely is under powerful leadership.
Car parts cheap today, much cheaper than yesterday!
Car parts are a sticky subject, not because they can be expensive but because they get sold to more than one manufacturer and their resale prices are oh, so different. I had the pleasure of befriending a mechanic whom showed me the margins made. Oh-Oh. Heater fan motor for a Golf goes for $38 compared to Mercedes $150.00. Same part number. And yes, it was a Bosch. So yes, when we complain about unreliability we often mistakenly look at the repair bill. Some parts are marked up over 1 000%. Luxury cars also carry a fancier labour rate per hour. Car part pricing needs to be monitored and if excessive the supplier needs to explain. Watch those anti-competition lawsuits.
Doing some research of our own:
Our own research has lead us to believe that the following holds true: (forums, tech notes, professional guidance from experienced mechanics and looking at workshop service manuals).
Previous driver history, not necessarily the car.
Your history book does not tell you everything.
Manufacturers should own up to problems that will arise after the warranty has expired. i.e. Radiator failure causing damage to the transmission.
Where was the car manufactured. German cars in Germany?
Is the dealership qualified to be working on your car? More often the small company private owner come technician in the grey overall has better quality control on the vehicles leaving his premises than a high end dealer.
Engineer change notices are not always available to the public.
Vehicle usage. Mileage means nothing – how was it used?
This list is virtually endless.
Most vehicles on the road have their own glitches, some not even pertaining to same year models. We have heard about the Monday and Friday manufactured car. What about the car driven at 24:00 hours after a visit to the local pub. Street racing and other little jaunts.
Germany is proud of their engineering ability, likewise Italy, France, British, America, Australia, China, Sweden, India, South Korea, Japan and even South Africa. It’s in their culture.
The Aisin Warner AW55-50SN and AW55-51SN automatic gearboxes are used in a wide array of motor vehicles on the roads today and gauging by the amount of complaints they should never have been manufactured or at least they should have been replaced by a better gearbox. That’s how the story goes in any event. Truth of the matter is that these gearboxes are plentiful and because of their popularity they would reflect as having a high failure rate but the true test is how many have been manufactured versus failure rate.
General motors have also used the Aisin Warner AW55 series under their naming code AF33 which is identical, also a trans axle designed to drive the front wheels. Whatever naming convention is used, AF23/33-5, FA57, SU1 or RE5F22A the reliability of these gearboxes has been more often than not taken a beating from car owners because of solenoid failure and usually expensive repair. Many auto technicians do not like computerised gearboxes and will refer the owner to a specialised repair center. Although the internet is full of DIYers completing successful repairs on the valve body it is ill advised to dive into the electronics or mechanical aspects of these gearboxes unless one has a full understanding of their inner workings and has the specialised tools. It is generally accepted that certain malfunctions can leave one stranded but the more cautious of us will be aware that a faulty gearbox can be dangerous.
