I finally finished restoring my Sony TC K96R and I'm pretty happy. All new caps, transistors, belts....It was a Goodwill find it even had the manual and wired remote. It was playing low on the left side but some adjustment on the left playback amp fixed it.
I have a recorder exactly the same model, also with problems, (probably capacitors) when you play a cassette it turns off after a few seconds, however I want to recover it because it is a beautiful machine, very well built and with exceptional quality. I have already received most of the components needed for the repair. I have the original paper SONY service manual. I have been following your videos, so thank you very much.
Very likely the servo board has gone out of alignment because of the caps getting old. All I did was replace the six bipolars, and that was enough to throw it out of alignment because of where those caps are in circuit. I'll cover the alignment in the next video, but you'll need an oscilloscope and a power supply to do it... I don't think it's even possible without those tools. I'll get to that part when I can, but I'm new to this so I want to take my time so I can get it right.
Thank you very much for the tips, they are very useful. Fortunately I have these tools and this is a project that I want to complete, not now (I'm with others) but I want to collect all the information so that I can successfully complete this project. Machines of this breed are no longer made...unfortunately. Now it's time to use it and throw it away....and buy it again. Thanks again.@@Oklawolf
I remember from years ago I visited a Best Buy to speak with a Sony representative that was there to show case new Sony products. I spoke to the gentleman about Sony reliability and he informed me that reliability was not a big deal customers could always buy another Sony product because Sony makes the best products. I thought he was very callous and cavalier. Fast forward a decade and I purchased a Sony 65" X90J. I read that it was considered an average LCD HDTV. WRONG... I am perfectly happy and I have not had a single problem.
@@Oklawolf If you can't save the filter, green nail polish works great and I know you have that ;-) Looks like mine measure 4,3mm x 20mm. These are axial leads, if you think they'll work, I'll send you a couple.
I'm sure those would work, and I'd be eternally grateful! Otherwise I'd have to pay the eBay scalper prices. JKL has the lamps, but Mouser and Digikey don't sell them for some reason.
Thanks! I just hope I'm up to the servo alignment job. Sony's instructions are a bit confusing, but I'm sure I'll get it figured out. Can't be much worse than trying to find the cause of the dead capstan motor for two days.
Not sure what you mean. I prefer Fix Your Audio belts for most high end decks except for these dual capstan direct drive units. In these cases, the thinner PRB FRSP8.97 is better. Both this deck and the TD-V931 (video in two weeks) have already very clearly confirmed that for me. However, the FYA belts usually outperform the rest of the PRB belt line, so it's only the FRSP8.97 I like right now. For not so high end decks, DeckTech belts from England are my go-to. They usually do worse than FYA belts, but not by too much, and they are usually way better than the cheap Chinese belts on eBay.
@@Oklawolf Thanks for the detail about belts, but my question was about the acronyms like FRSP, that the belt in your video featured. Sorry for the unclear question.
This is very nice deck i have serviced one for myself. Dont be afraid to disassemble those reel motors its not complicated as it looks like and also relube those pinch rollers arms - from my experience those were fused to their shafts and no play mode in the first place... Regarding capstans dont spin...familiar to me too, but on my part one stupid 10mh inductor near controller chip was 'open' and because of it all tape transport was actuality doing nothing - just imagine how much time it took to find that one faulty part... :))) In the end these k666es are very nice peace of engineering and they sound very nice and warm. Nice work! Cheers

man thats such a nice deck, i may have to get one myself for my cassette deck rack i only buy black decks and this one would fit in nicely

I bought my parents the 55” version of that set for Christmas a while back. Still working today.
I hate Sony , everything I've had of Sony has failed from vcr's to video camers to TV. Sony is all hype.
I wouldn't say they're ALL hype, but they've annoyed me about as often as they've impressed me.
I have sony boomboxes that are still working perfectly. I do prefer JVC over anything though.
La sony e' meglio di quanto credi,io ho apparecchiature sony e non ho problemi,a te e' andata male..
For the 1.5v dc supply, can you get away with using a fresh AA battery?
Unfortunately no - it needs to be a regulated 1.5V DC.
I have some 8v meter lamps, I think they're 4mm diameter, what are the dimensions of the one you need for the well?
Looks like it's 4.8mm x 26mm. I'm not sure I can save the green filter on it, but that's not a big problem for me.

@@Oklawolf Happy to send them. These are frosted but that won't matter for your purpose.

What do the belt types mean? Would love to learn more!

That's just the PRB naming scheme - I don't think it stands for anything in particular.

I’ll get it. It may take longer than I would like, but I’ll get it.
Your soldering job annoyed me a bit
