Wow. I loved this old deck and hung on to it even after it quit working. I took it to a pro repair facility a number of years ago. The took it apart put it back together charged me a hefty survice fee and said it couldn’t be fixed. Still I couldn’t part with it. So a couple of weeks ago I decided to finally just get rid of it but before doing so did a little more investigation. That’s when I found your video. I took it apart and sure enough all that’s wrong is just the disintegrated gooey belts. I’ve located belts on eBay and I’m going to tackle it. If this works out I’ll one happy dude. Thank so much

Nice deck - I have the Japanese domestic version of it (kx-1d). It's where I found the most unusual thing found in a tape deck - a nest of Asian yellow longhorned beetles. The evil creatures that kill North American forests but, fortunately, can't survive in my country. So, there was a big blob of cotton, about the size of the power transformer, and three starved beetles still clutching onto the wires. The belts (factory original, presumably) were loose but fairly solid.

The dreaded black goo left by the old belts is horrible stuff to get rid of. IPA does a good job, and leaves a clean surface for the new belts to grip on. Yamaha made some good decks in the early years, sadly it went downhill with later designs due to cheap motors and decks. Excellent tip of using a guitar tuner to check the speed with. Have a great Christmas and New Year.

26:30 - There is no wonder that there's no Dolby C. This deck and the Technics RS-M270x were rushed into production to beat Ray Dolby's new system (which would become Dolby C). With the CD launch imminent, the industry needed some magic snake ointment to extend the life of the cassette format. How about a new super-duper noise reduction? Enter Toshiba Adres, JVC Super-ANRS and dbx Type II. The dbx company managed to sign up Panasonic, who would design the low-cost AN6291 dbx IC. But it won't be released until 1982, so in 1981 Panasonic and Yamaha took these large dbx-designed NR boards and transplanted them into their existing (and already outgoing) two-head models. A few months later Sony, Hitachi etc. rolled out new Dolby B/C chips, and the war was over. Dolby had the whole market, and the dbx never took off, although Panasonic supported it until 1987 or 1988.

A good test for pinch roller is a 90 minute TDK D tape or equivalent with the almost fully loaded take up hub. If one unit is able to pull that kind of smooth and thin tape without fluttering the roller is fine. Anywhow... since most are the usual 13x8-6mm with 2mm hole jobbie worth less than 2 bucks each at this point in time the they should all be replaced. Since some may wonder: even pinch roller bearings must be lubricated or greased depending on the roller's bushing.

@@ctrlzyx2 9 out of 10 won't even notice that it is burnt out. If someone asked for the light to be replaced, I would replace it, and charge for the part and my time to go and get it, or for the cost to get it delivered. I don't stock all these light bulbs in the various voltages. Meter lights, yes they will normally be replaced, but the light behind the tape most don't want replaced, and that goes back to the days when I was working full time. When giving an estimate, I would note if the bulb was out and ask if they wanted it replaced. Even it is was just the couple of bucks that the bulb cost, 9 times out of 10 they said no. They especially said no when the unit came in for something unrelated to the transport, so there was extra labour to change the bulb. Used to change them for warranty work and that is about it. I don't know where you are, and people have endless funds, but here where houses cost 1.2 million for a tear sown shack, people just will not spend money to fix old electronics. They want it fixed for next to nothing or they will just buy something else. I got out of the business 18 years ago because there was no money in it anymore. Many shops stay in business from the estimate fee they charge. Every unit that comes in they charge 95.00 before they pick up a screw driver. They estimate very high hoping the owner will walk because they just made 95 for doing nothing. So they will quote on every last thing that can. Needs a full recap, 5 special light bulbs at 5.00 each, you get the picture. The odd customer will take them up and the rest say forget it. Many will tell this certain shop to recycle it for them. They fix it and sell it for big bucks in their retail store.
