Not only you've repaired it, but your explanation of the process is so clear and well filmed that this can now serve as instructional video for repairing cassette players. Great stuff!

Back in the 80's when we were 'backing up' Commodore 64 games on tape, we always found that high speed dubbing was much more successful than normal speed. I never knew why but my guess now is that the wow and flutter would be much lower because less torque is needed on the motors and they could run more steadily.

"Now this is real edge-of-your-seat stuff, the kind of thing KZfaq was designed for" genuinely made me laugh out loud.

Fair play! That is some serious work right there. Looks stunning! Especially with those reel to reel cassettes.

Thanks Mat for the video and to all the people who helped him to repair the machine . I love it when I see people repairing things and learning something at the same time. I enjoy your style very much. Best wishes.

I don't often comment. The community aspect of this makes me smile.

My Auntie is a dance instructor in Okinawa. She has the same tape player! She told me before she started using cd’s she used this player for her studio not only to play dance music but to also copy for her students to take home. She has now either converted those tapes on to CD or asked the record company to send her a cd remaster. Thought i would share.

Mat - The Reassembler; and just as enjoyable as James May.

Now you can go back to pirating music for all your friends.

I wonder if the people who designed these things ever see these videos of people restoring them years after their service life had expired

And the main thing - it looks bloody brilliant!

You are brilliant sir. Subscribing to this channel has been one of the best things I've done. I love how you engage with your audience and then how your audience responds to you in this passion of looking at yesterday's tech! I have one issue with you in that you often deprecate your skills sir. I think you are very technically minded and while not a factory trained technician you are immensely competent. You should claim your proper respect sir as it has been earned here many times. Thank you for sharing so much of your passion with us.

I love those old 80s style designs. The red colour on this reminds me of the old Konica Pop camera.

Fantastic Job. Thx to the community for providing the help.

Now i now why we need a 21:9 screen. It’s to use this cassette deck as wallpaper

Oh my goodness this video is GOLD. I recently unearthed my old 80’s lavender Panasonic boom box from my mom with hopes of giving it to my kid. But upon trying it out, it had a rattle aaaand it ate a tape. I took a stab at fixing it, found those exact pieces floating around (except the conical spring…) but the belts are clean and in tact! It has the same Tanashin mechanism, just a different motor placement. Your video now explains why my clutch gear wouldn’t spin! Hope I can find that spring and repair the split plastic cap, or I’ll be reaching for the superglue to mimic the sad solution of those cheap knockoffs … unless you’ve still got spares to spare?? Short story, this is the most satisfying KZfaq video I’ve ever watched. Thank you!!

The reason behind the better Speed and WOW/Flutter Values are more of plain physical nature rather than electrical. These closed servo motors are designed to withstand slow and medium voltage chanes and drifts. The motor won't spin any slower unless the supplied voltage is very low (6V or so). That's why many decks continue playing normally with bad batteries till the end, and then fail very fast in just a few minutes. The motor will draw more current when voltage is not availiable until both is not given anymore. Plus the flywheel to compensate for slight changes in torque. For the better speed value of the copy, that's simple. A recording recorded on fast playing tape will sound slow on normal machines and vice versa. Too slow recorded, plays too fast. Now D1 was 2% up and D3 1%, that's -1% Speed. As seen on The meter. For wow and flutter it's even simpler. More speed, less friction, less hick ups from the mechanism. There isn't that much electrical about the mechanism. Unless one starts to mess with the record path and BIAS. This can get out of hand quickly. Still, great that everything went so smoothly.

As someone who did stereo repair, in and out of warranty starting in 89. Ive done that repair a million times. Lucky for u it was just plastic split rings on the flywheel. More expensive units some times had metal E rings. Those things are a eye hazard and u never find them again in a shop environment when they go pop. U just have to have spares, but good job on the repair. Brought back memories, learn something new every day i always say.

Nice of the guys to help out with the part's needed

GREAT video ... no stupid gimmicks ... just straight foreword tech repair ... that three deck looks in great condition never seen one before so got my attention as have several of your other cassette machines. As an electro / mechanical engineer myself I am always looking to learn from other people ... never to old to learn. Sadly that build quality from Japan is no longer there with equipment made in other countries now days ... thanks for sharing your skills.

So happy it works now. It'll look perfect at a picnic or something

As a child, I loved using high-speed dubbing to rips tapes. I also used it on occasion to copy ZX Spectrum/Amstrad game cassettes though they were prone to fail unless copied on normal speed.

Great video when I saw the thumbnail of the radio I clicked on it. This radio reminds me of the dual tape player/radio that I had as a teen, it was White, Slim with two tape decks and had all kinds of neat features on it. Unfortunately it was robbed from me as a teen and haven't seen it in years this video brought back some great memories thanks.

I can imagine an 80's Japanese party DJ getting some pretty good use out of this.

Double-take on the triple-tape.

I stumbled on your channel by shear KZfaq luck, and I have stayed. Awesome videos.

That high-speed dubbing was a lifesaver back in the day when you had to make copies of your mixtapes for friends.

Good restoration, The manufacturer probably never thought this unit would be around long enough to require new belts!

Well done to both you and your audience. I couldn't resist playing High speed dubbing on 0.5 speed at 12:41

Thanks also to the guy who sent you a batch of the same batteries. But next time put them in the machine with the label in the same position.

It's baaaack. Glad you got it sorted.

I’m not a repair expert but I have an ultrasonic cleaner at home and whenever there is something small or annoying or hard to clean I just drop it in and it does a great job, I wonder if such a cleaner could save you from doing so much manual labor in the future. Thanks for all the great videos! Keep em coming :)

Wow that triple deck desktop background fits nicely with your ultra wide screen

I'm impressed with your patience Matt. Thanks for another great review.

I love how much time you put into cleaning and repairing these old pieces, even though you may only play it for the video and never look at it again.

Love your channel to bits, clean and simple! Have been a hifi and music enthusiast ever since I inherited my dad's hifi equipment when I was ten. Father succumbed to pulmonary cancer at the ripe old age of 35, God rest his soul, but his legacy lives on.

Without Techmoan and KZfaq,i wuld never have known these tri-tape players existed.KZfaq was originally made for these kinds of vids,as Matt himself said.Money was not why most people started youtube channels at its start,though it was a bonus pocket-change.

I could listen to Teachmoan say the word "Boombox" all day

A very interesting project. Really tiny parts on some of them. How lovely that people found bits of you and explained how to get it apart.

This video is a great counterpoint to all the negative comments. Those commenters ad nothing to the conversation whereas these commenters not only provided useful instructions, they also provided replacement parts! All of this came together to make another excellent Techmoan video.

"Gunk" and "Mush". Two of the most underrated words in the english dictionary.

I like the way the ultrawide boombox fits your ultrawide monitor.

You've really inspired me over the last few weeks. Since watching your videos, I've replaced the belts on my Sony HTC-NX1 tape deck, as they had stretched after 19 years of use, and also fixed my Panasonic RQ CW05 personal stereo after the belts stretched on that. Time to get some cassettes out to play on it!

9:02 Gosh, do i miss the *original* meaning of "designed to come apart".

I always love how you make me watch videos about stuff I didn't even know I'm interested in 😍🤣

I like this tape deck.You love it when everything comes together.Had a few repairs that went so well and most were simple and blind luck helps. Had a belt less dual tape deck and the one would not work.After awhile of trial and error I was ready to call it a day. I was picking it up off the counter and landed hard.I tested it to make sure no damage. Deck 1 that I thought didn't work started working. Blind Luck a happy accident caused it to work. It worked for years after that.I only paid $25.00 dollars for it.Until next time 🙂😎.

Apart from the content which is as good as always, I really appreciate constant quality across whole video, great control over lighting, exposure and depth of view. Also the sound level is stable across whole video which makes listening on the headphones a pleasure. Good job! 🎧🙂

My theory on why the High-Speed dubbing produced better results is because the flywheels are simply spinning at a higher speed, which allow them to conserve more energy and therefore better regulate the speed of the tape. Great video, keep up the great work.

Great video! Glad you were able to repair it with help! Great quirky machine! I still have my old cassette collection!

With your inspiration, I tried to fix an old cassette deck. It is absolutely amazing how messy those perished belts can be.

So glad you got it working. Something that I’d have loved back then, albeit for no real reason. It just looks so...

That is one gorgeous looking tape deck. Bright red plastic definitely needs to make a comeback.

Great job getting that awesome bit of the past back in 'like-new' shape! That's the best triple-cassette deck I've seen

Hi, i would like to say that I've started to watch your channel 2 months ago and I must say your context is great! Thank you

Two thumbs up for the people that sent you those parts and told you how to fix.

I love these videos! I'm not sure why. It's just a great mix of understanding technological ingenuity and preserving it, seeing products that were sold in regions that we may not know, bringing something back to life, educational, geeky... it's just a great mix and so well presented.

I bet you could defeat the mute and pause and get all three playing simultaneously. Great video, and nice job on the repair.

I had a two-deck player that COULD play two tapes at the same time. I'd amuse myself by playing the same song on both and see how they would go out of phase slowly.

And a busted "bugger to access while running" motor speed control is why I had to put a zener across it to slow down an over eager drive. This was back in my early impatient teens where replacing the motor pot would be too much work. It was a sony though. These things are so much fun to tinker, I hope they come back harder.

Have to love the little communities we have here in KZfaq, helping each other out to make videos

Great work on those Tanashin mechanisms! I've done a similar work with both decks of my Panasonic RX-CT 800 boombox that also uses Tanashin mechanisms but with the improved "full autostop" feature. Belts turned to goo so there was no fast forward or rewind and the automatic shut off always tripped as soon as a function was activated. The most annoying thing was cleaning that black goo from the pulleys and capstans.

Das habe ich noch nie gesehen. Und das qualität immer noch besser ist als heute ist auch klar.

I love how you perfectly use your widescreen in the background xD

3 cassette deck? Wooow! If you had this in the early '90-s then you was the king :D Briliant idea the background with a picture of this long beauti on a 21:9 display :D Well done video!

What is not to love about your channel! Not pretentious, technically savvy, nice dry sense of humour (I spelled it your way😉). Great work as always.

Techmoan is quite possibly the coolest youtuber on the youtube

17:09 Japan 1985 vs China 2019.

Great fix and very well done on the repair, I kinda like this radio cassette! I genuinely thought you were gonna treat us to a puppet show at the end about why we needed 3 decks on a boom box.

Well done team Techmoan, great result. 👍

I've repaired a bunch of these. Those two different mechanisms were perfectly interchangeable. You made a repair that should be extremely simple way more complicated...

Brilliant to see it working! Hat off to all the people who helped and donated the pieces.:-)

This channel gives me warm fuzzy feelings

Best prescription for a soggy Sunday morning.

It's nice to see something built not as high end but not as crud either. It is exactly what it says on the box. No more and no less. Honest product advertising.

One of your best videos so far I think. Explains a lot, nice detailed shots and you look happy with the results.

As John "Hannibal" Smith would say, I love it when a plan comes together.

I'm now convinced that it's time to start working on some of my old decks where the belts have turned into goo... Thanks for the excellent, step-by-step explanation of how you accomplished this repair.

This was cutting edge tech for 1985.

That was really nice that that guy sent you all of those assemblies!

I actually love the aesthetic of it

Great video ;) I love these japanese consumer electronic’s videos. Please talk about Yamaha,Pioneer,Sony,Sharp and so on. Good production and quality = Good value so keep doing what you have and i will support you if needed.

I always look forward to your videos. Thanks for all your hard work on these! (Also, I am a big fan of the puppets)

I just have to say this video is hugely motivating. It is such a joy to see the satisfaction in your eyes after dealing with a reasonably difficult task and nailing it. Well done Sir and respect to those that helped you get there.

I don't know how you manage it fella. I've just watched a 20min vid of the cleaning and restoring a cheap plastic tape deck and enjoyed every minute from start to finish. Kudos on that and kudos on the acknowledgement and thanks you gave to the assistants who all get a their own kudos points. Cheers all round!

All around this video has restored my faith in humanity.

Glad you got help with getting parts needed to repair your deck.

National! I hadn't thought of that brand in years. I had a National shortwave receiver back in the 60's when I was a kid. How small the world has gotten since then.

16:57 - it is quite attractive with the different coloured tapes working at the same time (plus, I like the colours you chose).

Love those tape color choices very cool.

Amazing job! Great to see it repaired 😀

I remember when i was a teenager, the guy i used to buy my mixtapes off of had a boombox with 2 tapedecks that held 2 tapes in each deck for a total of 4 cassettes...

Oh, that's awesome, glad it was able to be fixed. I do love watching things getting taken to bits and being repaired. Also, bloody hell I love that depth of field in the studio segments. It just looks so good.

Awesome to see some unique 80s audio technology and awesome the viewers sent in info to repair it - much better than today's 'disposable' products.

This is exactly why I support your patreon and youtube. I am happy that little machine is back working and you got to tell us about it.

If he mixed the batteries again, I'm calling Interpol!

Very cool machine, great detailed repair. Never knew they made triple cassette players.

I don't say this enough but, Thank you for your very high quality content! I love music, i'm no audiophile but I really enjoy good engineering and having a look at all the gubbins inside all manner of things (from my beloved Vectrex to the world renowned Naka-Dragon!). One day I'd love a video of you simply talking about some items you'd love to have in your collection is price wasn't an issue and some of the most over engineered items you are aware of, but in any case - I really enjoy your content and Thank you dearly! =)

I'd take this over the rubbish you featured the other week that came from Aldi!

All of this overwhelms me with thoughts of thinking about, "Wow, when I was younger, I thought hi-speed dubbing was the cat's pajamas." Then, I think about the thought of hi-hi-speed dubbing, and everything would sound like a Picasso.

Very cool, nice job. Also, I love your multi-colored metal reel tapes.
