AIWA SYSTEM 22 - Micro HiFi from 1979

I'm an electronics technician and I've been working on units like this since the late 1970s - around the time these systems were brand new! Consequently I have a lot of experience working on them and I'd be able to sort out all the little issues these have in short order. I also have access to a wide range of parts, the likes of what were used in these machines so repairs generally aren't a problem. It would be unusual to get a system like this today which didn't have some kind of fault. By now, most of these units are 30+ years old and things wear out, belts perish or harden, capacitors and other parts need replacing and anything mechanical will need some cleaning, alignment and lubrication. The beauty however is that these machines were made to be repaired by human hands, unlike most of the modern stuff which is now made by robots in factories and designed in such a way that they're not able to be worked on, even if you can get the parts.

[@mikemidulster]

I'm also an electronics technician since the 70s and worked on this stuff too. As Technomoan says, unless you can work on one of these yourself it's really not economically viable to buy one, as the amount of hours required to make a system like this work like it should, would make it a very expensive purchase in the end. I was never attracted to these micro systems as the small speakers let down the rest of the system.

The speakers look fine to me. And the grab handles are essential because it was intended as a rack mount system. They really don't do consumer electronics this nice anymore.

When I was a young Army private I used to go to the shops to daydream about the latest stereo offerings from Japan, back in the early 80s. As I didn't make much money, it took me about 18 months to save up for a proper stereo system. Things were definitely built with looks in mind as well as sound output back then.

[@JoeJ-8282]

Yes; you are correct about that being only an analog tuner with a "digital" frequency readout, as I have seen a few other components like this also, (usually either very old tuners like this one, OR very cheap quality if new), and this specific tuner in this video sounds like it has gotten out of alignment because of bad capacitors over the decades, so it could definitely benefit from a rebuild in that respect, by someone who knows how to adjust and align analog tuners correctly!

[@DJNickYouTube]

I'm sorry but for me, electronic technician since 1985, a "digital tuner" is a PLL synthesised tuner, not an analogic tuner with a "digital readout" of the frequency. You are free to think as you like, but electronically speaking, my definition is the exact one (and only).

[@ColmGibney]

My father bought this system for my mother in, I think, 1979. We had it stacked in the reverse order to you, from top down: amp, pre-amp, tuner, cassette. It was mated to a more serious set of AIWA speakers, the model I don't remember. People always commented on how well it looked and sounded. It was more than loud enough for a large room in a large house. It served us for twenty-plus years. The cabinet remained solid to the end. It was a pleasure to own, and it is a pleasure to see it again here on your channel - thank you.

[@EvenTheDogAgrees]

Hey, Matt, a neat trick to temporarily shrink the loose belt is to dunk it in hot water for a minute or so. It won't hold up, but in a pinch, it'll get you going while you wait for a replacement belt to arrive. It doesn't matter in this case, as you're only missing out on the tape counter, but it's a good trick to have in your mental toolbox.

[@RealEpikCartfrenYT]

i boil the heck out of my belts, like 10-15 minutes. they shrink but i've boiled one out of my Philips boombox, that I play tapes in a lot, and its been months and the belt is still good. wow and flutter is also relatively low

[@EvenTheDogAgrees]

@@RealEpikCartfrenYT yeah, it can last a couple of months, but eventually they fail again. I learned this trick when the CD tray of my XBox 360 failed to open back in 2015 or so. Boiled the belt, worked like a charm. But it didn't last. So best get a new spare for when the old belt eventually fails on you again.

[@wbfaulk]

As for the "22", it's designed like rack-mount equipment, and racks are often specified by a non-obvious dimension. While the setup you have doesn't hold the units in place with screws, that flight case at 3:18 makes me think it was an option, so it might be that the 22 is the distance between screw holes, maybe on-center?

[@rolfs2165]

Yup, that might very well be the case. The width from the left edge of the left ear to the right edge of the case looks to be 22cm, so if the screws are centered on the ears, that'd be it.

[@osgeld]

every real rack system I have ever worked on is 19 inches wide and height is specified in units, 1U = 1.75 inches, 4U = (1.75*4) 7 inches

We had a AIWA mini system that was a "Boots" badged product from the early 80s. Great system that lasted over 30years. Infact it was very similar to this, so probably a later evolution.

[@garyt123]

You get like for the idea, but I just measured mine and its 23.6cm from the outside of each 'handle' to 'handle'. They don't actually have bolt holes, just a removable rack handle. Distance from the centre of each handle is about 22.8cm

[@Stoney3K]

Makes me wonder if AIWA also provided 'flat' rack ears which accepted screws, for mounting in the flight-case style of cabinet.

[@herbertweixelbaum]

22 might be the depth of the unit(s).

[@garyt123]

@herbert weixelbaum Height is 71-72mm. The Power amp is a tad taller at 72mm. Depth is _very_ variable, again the Power amp in the deepest, at 24cm, the Preamp is only 17.5cm. The Radio, without the AM antenna is about 17cm.

[@tad2021]

22 might be the rack width. If the ears had mounting holes, they would likely be 22cm on centers.

[@alasdair4161]

I thought the same. I made a set of rack ears for my first CD player that were oversized to fit (19") and it looked factory original as I used similar anodised aluminium.

[@pseudotasuki]

Yeah, that's what I was thinking. The distance between the bolts is what determines compatibility.

[@patricklepoutre]

[@wbfaulk]

​@@patricklepoutre19" racks have 17¾" of free space between the rails. Mat said that these cases are 20.5cm wide, which would put two of these at 41cm, or slightly more than 16⅛", which feels like an awkward gap to fill. I really like your thinking, but I'm not sure it works, and it still doesn't explain the "22". Maybe a 22cm-spaced sub-rack that can be mounted in a 19" rack?

I purchased one of those new in 1979. That then was one of the classiest hi fi’s on the market, maybe the first mini hi fi. As regards to the speakers, they were sold as bookshelf speakers, a new concept then, which were sold along with the hi fi. I can tell you the loudness you could get from those little heavy speakers without blowing them was awesome.

Thank you! In 1980, 17 year old me used to go to my local TEMPO store to play on the Atari and work out what o spend my apprentice wages on that month. They had the "AIWA Micro sytem playing all the time. I used to look at it and dream I could have one. All I could afford was the Amstrad stuff or Solovox. I was looking for this recently to see if they were still about. You get lots of results looking for AIWA Micro sytem. Now I know it is AIWA SYSTEM 22.

I Have A 1977 Leek Amp 3400 And Have Always Turned Volume Down To 0 When I Turn It On To Save Speaker Damage, Its A Very High volume Amp..👍

Not really a problem with the order. The manual for the Aiwa (and my old Rotel) advises turning the volume down to 0 when switching off (and it would, presumably, stay at 0 when you switch on, kids and grandkids permitting, of course, so always worth checking before switching on). The Rotel has fuses, which did blow that one time back in 1992 when I forgot to turn the volume down. The Aiwa (neither the P22 or C22) doesn't, which makes me think it does have a protection circuit. However, mine has been working for 45 years now, and I'm not going to test it to see if it does, and if it works 😂.

[@derekporter7658]

Loved Aiwa kit, the best were Akai, Aiwa, Sharp, Pioneer, Technics, SAE and Trio. Loved all that separates stuff as well as their other stereo systems.

[@MrSlipstreem]

FYI: 'hi-blend' doesn't make it mono. It reduces the channel separation at high audio frequencies. The vast majority of additional hiss from an FM stereo decoder is at high audio frequencies, so this provides noise reduction without defeating the stereo decoder altogether. It was very easy and cheap to implement as it often only required connecting a low value capacitor between identical points on the left and right audio channel circuits internally with a switch in series to disconnect it when not engaged.

[@1dolar1note1]

I do hifi repairs for a living, exactly the stuff you show around on your channel is the stuff I get my hands on pretty much daily. We get stuff from all over Europe and have found a lot of trust within the German Tape deck enthusiasts communities, so it's good to know that despite the age of cassettes and tape decks we are one to get them to work even in this current year. Unfortunately it's a dying industry, almost nobody wants to repair old hifi anymore. The lack of schematics makes it difficult, and even if you get schematics and can make use of them with your electrical knowledge.. where do you get parts like for example the tape deck? There are of course sources to get alternatives that can provide parts that will make a repair work, but its again a very niche industry, we at my job are lucky we get the parts we do. I could self promote the shop I work at but unless you want to ship stuff to Germany (we have partners in the UK, nobody likes shipping in and out of Europe..), I wouldnt know what to suggest. Depending on where that VU meter on the tape deck is getting the levels from it could be a transistor in or near the output stage. I'm sure you've packed it away already, but next time try recording a cassette in stereo and check with another deck if both channels are present. Not what I'd do if I were repairing it but I don't think you'll want to poke around a circuit with an oscilloscope while the mains power is on lol.

[@juandenz2008]

How do you even get parts ? I'm sure there are some replacements that could be used for things like capacitors, but I was thinking a lot of parts would be impossible to source.

[@StealthCampADL]

@@juandenz2008 Most of the parts would be available, just some wouldn't be in quite the same package. The tricky bit, as mentioned, would be the things like the tape mechanism. Caps. diodes, resistors and the like are all much the same as they were though. Getting some values exact on some parts might be tricky, depends on the parts.

[@StealthCampADL]

I've taught myself board level repairs for PC stuff over the years and the most common failure is capacitors. There have been some dreadfully cheap makers over the years, but I've seen even good ones fail in similar boards. I've replaced other IC's, like RAM, but a couple of capacitors usually does the trick. And then, if I'm doing one or two, I might as well do them all and avoid trouble down the road. The other common problem is battery leakage.. This is where I learnt to keep my bodge wires as close to original length as possible when doing a track repair.

I have a 22 system, which I did use till about 5 years ago, mainly from my PC (via a phono to headphone lead), the tape deck never worked as the belts were all knackered (I had a 90`s Sony micro system tape deck on it instead), then the power amp lost a channel (after many years of daily use), so I replaced it with an early 2000`s Philips micro system (which has also subsequently lost a channel!). I must get round to re-capping the power amp on both! I have them going into some mid 90`s (large, 6" bass drivers) Wharfdale speakers, & I must say, the quality is perfectly adequate, & the bass is more than enough to distort the Wharfdales & disturb your neighbours 2 doors down! I have recently added the C22 pre-amp to my KAM record deck (which needs one), into an 80`s Hitachi ghetto blaster which has a phono in, & it still works nicely! If you look on eBay, Japanese & American spec ones do have a power lead daisy-chain setup (mine doesn't either). Its also worth noting the 2 channel LED on the tape deck, which changes from green to red in record mode, that was VERY advanced for the period! I`d also say clean the tape deck, with your Allsopp 3, or a few alcohol soaked cotton buds! I would also like a later Aiwa micro system, ideally with a graphic (there was one, cant remember what series, maybe 24?)

As a teen I had a cheap SABA 90's mini system, but with remote and fully electronic dual autoreverse cassette deck and 3-cd-changer. Now I collected the Yamaha Classic Line and the Onkyo Separate Collection (both from around '96). Back then I would've never been able to afford those. They just look so classy and high-quality and have some very decent specs. The Yamaha system looks brand-new. Both with the top components of the series, 3-head deck, CD, RDS tuner and amplifier and all remotes, manuals and cables. I restored them to working order, changing belts, swapping microswitches, replacing some capacitors, adjusting quiescent currents, replacing relais, etc. Electronics are a hobby of mine. I had a lot of work with the Onkyo deck, it had a lot of issues, and it's quite difficult to get to parts in the mechanism. But the reward is a nicely playing 3-head deck.

Damn my grandpa was obsessed with his hifi sytem. He always had to have one

[@jeremyfine1464]

I'm not your grandpa.!

My dad had this system on his boat with Realistic speakers and it was AMAZING! Thanks for bringing back some excellent memories 😌

New Techmoan video at 4am? Sleep can wait lol, love the content!

[@beitie]

I'm pretty excited for the next one. I remember the Aiwa systems of the late 1990's and early 2000's, they were in every single one of my friends homes. I always thought they had decent sound to them as well. As far as the repairing of old systems goes, I understand the struggle. I myself cannot solder to save my life, so it really limits my personal abilities. I had a wonderful shop in my hometown called Tomtronix that I used to use for some repairs, but sadly he has retired and moved on. My current hobby is collecting and fixing up Bang & Olufsen audio equipment from the late 1980's through the 1990's. With that hobby, I've been really lucky to meet someone who does not live too far away who can solder really well, so I've been able to keep a lot of equipment alive that would otherwise be tossed out. I would love to see your experience with B&O gear on this channel because I think it's some of the most fascinating hi-fi ever created, and the sound is very good as well.

[@pengiswe]

I'm thinking if 22 refers to the width as the distance between the mounting holes if it would be mounted in a rack with screw mounting. What is the diatance between the screw holes of the "ears"?

[@DisgruntledPigumon]

Micro systems are still going strong in Japan, and they’re super high quality. I’m still considering getting one for the office.

[@SvDKILLSWITCH]

2:45 Missed opportunity to call this a "micro" series

[@computer_toucher]

Before getting proper studio monitors I used a pair of 3" one-way speakers pilfed from an old JVC micro system. The speakers were wood! Proper wood! And they sounded fantastic for what they were, on a late-70's Kenwood amp.

I’m never happier then when you have to try and fix something! You’re so informative, entertaining and calming! Please keep up the excellent work sir!

[@WalksInCamera]

This reminds me of wandering around Laskeys, Comet and Richer Sounds years ago, although it was fairly impossible to wander around the old Richer Sounds in Bristol (Cotham Hill) due to the limited floorspace!

[@jamesbaker429]

Always the smallest size of store stacked to the ceiling sound rooms an afterthought for later resights of stores.

[@WalksInCamera]

@@jamesbaker429 I still have an Aiwa XC700 CD player from that small Bristol store. When I moved to London found the old London Bridge Walk store was even smaller! The old style catalogues were great.

Matt, If you are looking for repair that picks up where your ability stops then look no further than Dengie Electronics. Having used a coupe of repair services previously that either failed to repair or said would not touch something that I had been attempted before, or they did not have the skill to diagnose correctly - I came across DE who successfully repaired a vintage tape deck for me not only fixing the issues but notifying me of other optional maintenance that would be beneficial. Another time a CD player had issues and one was it needed a new cog which DE supplied plus control panel dial knob / buttons that didn’t work. Not was it fixed but but DE went the extra mile in cleaning and adjusting things all part of the service. Excellent value for money and quicker than expected repair time and more that fair return courier cost. On top of all that the level of expertise and skill and knowledge is 110% impressive. This month I had a 300 disc CD player that had been dropped - as part of the diagnosis I was sent photos of cracked power board, bent chassis, 3 plastic supports that had snapped and a plastic column that held the drive that was broken. All repaired and excellent value for money the same week as sent in.

[@curcapsicum]

Nice! Looking forward to the next 2 in this series! Shame this guy is so run down, it visually looks great. Probably not even worth the cost of getting it repaired (if they could, like you said) for actual use, but for collecting or display, what a beauty!

[@baronbokaj]

Thanks Techmoan, love your compassion, and can relate to it. I bought a similar Aiwa system 22 brand new when it was first released in the 70s. I used it for a few years but soon found more powerful stuff. I recently found it in the cellar, neatly packed and preserved. Now its residing on my desk next to my computer and works flawlessly with the exception of the cassette deck that needs some oil and fresh "rubber". I love the brushed steel design, the handle bars and the sturdy switches. Aux 1 selects audio input from the computer / Internet and Aux 2 from my Sony Discman that I placed on top of the stack. The system is still powerful enough to upset the neighbours :)

There's no question you should send all your electronics repairs to Mend It Mark. He has a phenomenal KZbin Channel. Literally can fix anything. And, is in your neck of the woods.

[@telski33]

With the cabling it was probably on purpose to hi-light the fact these were separates which had it's own cachet

[@resofactor]

Eff me, this is the FIRST time I'm hearing about this system. Looks great! Love the modularity of it!

[@CarlosPerezChavez]

AIWA! What a beautiful name that brings back memories from the 80s: inexpensive portable cassette players, reliable and with great sound.

[@alexzovic5799]

I got recently this Aiwa 22 mini rack. Pair this little guys to serious speakers to feel the real punch. I have them connected to CANTON GLE-50 (same age as Aiwa 22). Simply amazing sound (without Loudness on). For me this is a holly grail among the vintage mini systems. Fun fact: it looks so vintage that always appear black & white, even on pictures taken in color. :)

[@RogueTrader-]

Same but i have them running some 200 watt Rogers LS7's which it drives effortlessly. Btw the loudness button- These are meant for listening at very low night time volume levels as it brings up the level of high and low frequencies. If you use it at normal listening levels it usually makes everything sound too harsh.

[@Bokooda]

Just watched Adam Savage mention you at the start of his video about his Sony TC-510-2 reel-to-reel tape recorder...

[@PBeringer]

33:14 ... Oh, I hear ya there. Forget classic cars, my "forty-odd years old" human body is a bit like that hifi; lots of components, but few working properly. Thanks for another great video, Mat! Looking forward to the next two in this series.

[@BeeDotEee]

The amp nicely warming the tape deck

[@HamburgerAmy]

micro hifi systems have always been my go-to "plug n play" upgrade to PC computer audio whenever someone bought an audio card and wanted a feature rich and good sounding speaker system to match that sits pretty on their desk. ♥ love em so much.

[@Firkinnel]

What a contrast to that crappy amstrad hifi you showed previously !

[@davidshepherd265]

My Dad bought an Aiwa boombox new back in the 70's when he was working overseas. Loved that thing as a kid, it sounded good, went loud and had a line input so I could plug stuff into it. Mum still has it, still works, even the cassette still works, still sounds great, though the volume control is a bit crackly and only one channel works, no matter if you're listening to the radio, a tape, or something connected via line in.

[@PhilipCockram]

Interesting episode . Trying to repair older stuff and maintain it for regular use really is a passion and hardly ever cost efficient . I've upgraded a few older RC trucks and replacing the electronic components is easy and affordable , but because other wear and tear or breakable parts are unobtainable. it makes using them difficult . I save them for special occasions and my ' daily drivers " are ones that you can get parts for .

[@andypalm7061]

Sweet! That cabinet has the look of a Dealer display unit. I just love these things. I I have gone nuts finding, restoring, Sony-Denon & technics “mini systems “ fantastic sound!

[@RegebroRepairs]

Yeah, as a UHER fan, that Uher version wouldn't hurt. :-D But it seems quiet unusual.

[@UK_Lemons]

...and definitely not up to audio quality of UHER manufactured recorders.

@@UK_Lemons Yeah, it would end up as decoration, mostly, which is a bit of a shame.

[@rabit818]

Linn used to make small(er) audio gear. Teac has a recent reference line that is quite small. The space you save on the Aiwa mini component, the ac cords take up. I like the rack mount handles.

[@andersondamasceno]

Maybe the 22 is just a catch?

[@evileyeball]

Thanks to the Microsystem haha. My mother upgraded to one in 2008 and I got their old 1982 Technics SC-2020D Package System which I wanted. with SL-D212 turntable, SU-V16 Amplified, ST-S16 Tuner, RS-M16 Cassette Deck, SH-523 Audio Rack, and SB-2020 Speakers. Some Deoxit in the Volume Pot is all I've really ever needed to do aside from a new Stylus :)

[@Lucien86]

That wooden cabinet looks like its suffered classic glue failure. (usually through glue drying out) Should be quite easy to get it as strong and as good as when it was new.

[@USSMariner]

Yeah, just saturating the joints with titebond and clamping everything down should shure it back. Corner clamps ftw

[@fastamx069box8]

Hey Techmoan, Love most of your videos for many years. I can that since the early 70s I have never had a Micro System. I was about 14 when I started gathering components and have never looked back. Please keep your videos coming. Your presentations are really good and very informative. God bless. Cheers

[@smvwees]

I wonder how your Dolby S cassette recorder fits in there. Or was that too wide being of a Midi size system?

[@Techmoan]

I haven’t got it to hand but a search online seems to tell me the Sony La Scala set was 31cm wide…if accurate, that’s another 10cm or so over the sys 22

[@groovychocolate]

Wow you just gave me a flashback to a long time ago, I had that exact Kenwood system at 0:44 , still miss it!

[@truecrimescotsman]

It's Saturday, a fine May morning, a Techmoan video about an obscure piece of kit that he never really got working. All is well with the world!

[@glonch]

Great video. Back in the late 80s, I picked up a Sony FH-606R mini system. Worked for about 20 years unit the amp died. The neat thing was the individual units were connected via ribbon cables for power/audio/comms so it was a really clean setup. The unit was locked together with two plates that also would hold the speakers. As time went on, I expanded my CD collection and got wooden CD holders (I think they could hold 100+ in each. They worked great as speaker holders too. Move the brackets from the unit to the sides of the cd holders and they would float the speakers. Nice stereo separation vs attached to the main unit.

[@sf-dn8rh]

Still have my dads vintage system

[@onefatstratcat]

Pioneer or Sony? :)

[@aagevaksdal]

My sister`s boyfriend left an identical setup without the frame, with us at our student flat in 1983. I really loved that system, remember that it was wery powerful and good-sounding for it`s size. I was well versed in great consumer sound, my brother had all the best gear from Sony and Technics at the time. I really want a set like that for sentimental reasons.
