Yamaha KX 670 Cassette Deck Repair

[@brianwood5220]

Thanks for the video, Tony. Good to see your still on the mend. Please take care of your health, those special people in your life really love having you around. Thoughts and prayers and thanks for sharing with us.

Great video, thx! My Yamaha KX-490 is working perfectly 😄 And so are my 200+ cassette tapes, all high-quality Maxell and TDK. They still sound like when I recorded them (up to 35 years ago). Keeping this deck healthy is relatively easy: - don't play crap-quality tapes - use the deck regularly - clean the heads with alcohol - as you say, clean the pinch rollers with window-cleaner, because alcohol is not good for the rubber - demagnetize a couple times per year, if you have a 3-head deck I'm told that a 2 head deck (like my KX-490) doesn't need the demagging, because the play/rec head demags itself during use? But I demag anyway, including pinchroller axis and other metal parts inside the cassette bay.

Thanks for the video, Tony. I have the same deck, also serviced - love it. It can really "squeeze every bit of frequency response" out of every tape with automatic or manual calibration. The only issue I have with it, being two capstan tape mechanism it is sensitive to the quality of cassette plastic moulding. The opening erase head goes into on a single capstan player is taken by the second capstan. And since it's a 3 head deck, the only place for the erase head is the narrow opening in the cassette tape path. It's not an issue with good cassettes like TDK, BASF etc. But I have a several factory pre-recorded tapes (mostly from 70x-80x), cases for which were made using not the best quality moulds. The erase head doesn't fit into that narrow gap, causing the heads not to engage fully, so no play. The solution is to either use a scalpel to correct the bad moulding of the cassette tape or play the tape on another single capstan deck (I am using my NAD for that ).

Electric light Orchestra, Mr. blue sky, Had to stop Tony's stream and listen to Blue Sky. Thanks Tony

[@Poppinwheeeeellllllieeeeez]

Nice Tony. The metal construction on that deck is classy.

[@mikesradiorepair]

I just rebuilt my Nakamichi Dragon tape deck a few weeks ago. I purchased it new in 1989 when I was in the Army and stationed in South Korea. The continuously adjusting azimuth adjusting replay head is a work of mechanical / electronic art. Nobody made tape decks like the Japanese back in the late 80's and early 90's.

[@adaboy4z]

I have the KX-930 and 380 both cheap estate sale finds. Little refurbishment and they are excellent players/recorders.

[@guyfromsac1]

I've always loved Yamaha 3-head decks. Along with Denon, Akai, and Nakamichi, they're my favs ...

[@febobartoli]

I still have my Nakamichi cassette deck and my Rotel CD player stereo system. Thanks for another great video. If you have a link to the plastic clip removal pliers you used, please add it to the description!

[@Davor-hifi]

Really interesting that you guys in US don't have at least one store that sells belts. I live in Croatia and i always order stuff from Thakker cause like you said he got some quality stuff. Other then that keep the good work. I always enjoy your videos.

[@unclefrogy743]

specialized tool as well as the parts they are designed to work with have names but they are seldom labeled. That is true for a lot of electronic parts including connectors. they are standardized common and unlabeled. That makes it very hard to look up either connectors or the specific tools needed .

[@bdw5821]

Tony, thanks for the video. I really enjoyed it.

[@mikepxg6406]

Yamaha made excellent Cassette decks.

[@TMG363]

Nice job Tony. I was hoping you were going to go over there. Head adjustment for optimum clarity but that short bit of rush sounded pretty clear to me!

[@xraytonyb]

I showed how to do a head alignment in the Pioneer CT-F1250 series. Although it's a very different cassette deck, the process is similar.

[@anandadesilva6558]

Hi Tony, Tu er dial strings are my favorites!

[@dimitarkirchevdimitrov6321]

Hi Tony, Great video as usual 👏👏👏 Hopefully those red caps on the right side of the main board which is I guess the the playback circuitry of the deck are not the famous for leaking red elna duorex. They are widely used in the top Sony ES series and are notorious for leaking in almost every cassette deck they are used. Just double check 😉

[@xraytonyb]

Thanks for the warning. I'll check it out!

[@ewhibs]

Love Mr Blue Sky. This summer we saw Elvis Costello, 70 and Daryl Hall 82! I would say time has caught up with their voices to some degree but we loved it the nonetheless :)

I still got a reel to reel !!

[@duroxkilo]

i'm horrified of tape decks :) i bought tapes at garage sales that are now almost 50yrs old and still play, like willie nelson 'the sound in your mind' from '76... just the other weekend i got a cassette player from my neighbor across the street ("general electric model 3-5151b") w/ just minor issues after about 40yrs. it's playing CCR rollin' on the river cassette ('88) right now :)

[@fabricehaesendonck196]

thanks for sharing your experience buddy!

[@zambrano966]

Excelente Tony, una reparacion facil y corta, muy diferente al video del Pioneer CT-F1250 que hiciste. Claro al final ese Deck quedo muy bien, creo que es tuyo y todavía lo conservas. Tony una pregunta, cuando hiciste ese video del Pioneer me acuerdo que compraste un trasporte donante para cambiar una pieza en uno de los Reel que estaba deformado, dime si lo tienes y lo vendes, tengo un CT-F950 y cuando estaba desarmando el Take up reel se me partio la pieza que sujeta el eje, no lo vendes ?

[@nabun00bs]

Always top notch informative entertainment!!!

[@Silent-Lucidity]

We're going to see Styx on the 17th of Sept. Unfortunately, Foreigner won't be at this show. It's a small venue, so maybe they decided to skip it to rest up. My wife's favorite band is ELO. She's not into vinyl but bought one of their albums so we could listen to it together.

[@dh-_1011]

ELO is alright. My favorite is New World Record. They put on a helluva show! Nice repair, by the way. Get better so you can fix that Sansui 9090db you have hiding somewhere!!!

[@therealdjryan]

I love the lanyard!

[@akkoa420]

Thanks again for another detailed repair, unlike you I am a collector of cassette decks, that doesn't mean I like working on them, however I like working on mechanical gadgets so I may not invent new swear words while working on them.

[@alex1520]

Surprised the video is only 50 mins long. Most tape deck repairs/servicing videos go on for hours and hours because tape decks are usually a pain to service with all their moving parts and both electrical and mechanical adjustments needed to properly align them etc; not to mention the headache with trying to track down the cause of w&f issues which are not always the obvious things like a pinch roller/idler issue/motor issue. I would like to see Tony do a reel-to-reel restoration, maybe a Revox or Studer deck - not for the purposes of seeing Tony suffer and have more hair fall out but because there's simply a lack of detailed videos out there that go into restoring those decks

[@len9518]

Tony...Apparently, you can repair anything. Do you fix lawnmowers? I've got one in mind.

[@ZiGLH]

I love ELO too❤

[@PhilipsN2552]

I like working on cassettedecks, but I do hate restringing tuners. New curse word? What about soldering a bulb connector wire, in 'your' Mac 1700, and cutting with a drop of solder my Mac's tuner wire in halve. That was a moment I invented a new curse word!

[@NICK-uy3nl]

Does anyone still listen to cassette tapes?????

[@michaelturner4457]

@@NICK-uy3nl I think, only to listen to and/or to archive old tapes.

Have you guys thought about converting your cassettes to MP3 so you can listen to them anywhere or send them to anyone!

[@Attraktionbyran]

Keep up the good work you do 👍

[@michaelpelley2815]

New swear word... I was thinking the same thing 🙂I had a K-320 back in the mid 80s that was a great playback deck - nice and simple. I still have my JVC KD-V6 (with wired remote!) but I need to have the belts replaced, etc. When you get your spec system all done, will we be getting some pictures or video?

[@applecorc]

34:50 wow that's a lot of electrolytic caps...

[@lithiumstatic]

😎

[@deekay2]

People that should admit themselves to Recappers Anonymous would tell you that every electrolytic capacitor in that deck should be changed due to age regardless if they are perfectly fine.

[@dirtydon8661]

Hey Tony, what size wire wrap/unwrap tool do you use for older Pioneer gear.
