A tape deck that was headed to the scrap heap. Motor damaged by owner trying to adjust speed. Will a motor from a totally different unit fit? Lets find out.
Yamaha's Play Trim adjusts the treble response on playback before the Dolby section to help it track and decode better. One of the best features I've ever found on a cassette deck!
That's right! I've had a deck like this since 1994, but everything is still original. I recorded it on 650+ cassettes and approx. he has played it three times as much, often for hours..., flawlessly! It has a nice sound when it has warmed up, after about 1 hour.
Never have been dissapointed wth Yamaha gear. Rx-V 1000 and 1500s are great amps. I like vintage yamaha speakers. Built well and still sound great almost 50 years later.
Another excellent repair and great that you saved another tape deck. My local charity shops haven't had any tape decks in for a long time. Either to do with covid, or there just isn't any decks around that people want to get rid of. Keep up the good work.
Well that worked perfect, the resistor did the job :-D i like the nice heavy flywheels, smooth out the fluctuations. No i didn't notice an obvious error. Now you have the faulty motor, maybe fix the preset for another tape deck. A game of musical chairs :-D.
I once tried re-winding one of these motors with no success. Did manage to get it spinning fine, albeit with some smoke. My only guess is the control circuit was shot and was the one smoking, but i don't know how to test those so I just left it as is. When deck A fails you always have deck B to play around with :)
My KX-580 has auto tape tuning too, what it is supposed to do is to record a tone on the tape then rewind itself and play it back adjusting the bias etc. automatically to tune the tape to optimise recording. It actually does a very good job, but like most auto calibration systems isn't always perfect, and with some tapes minor manual tweaks might be needed to get the best recordings.
@Taco this deck has a build-in tone generator which is the baseline. playback head compares the recorded tone with the baseline and adjusts the bias accordingly. there is no separate test tape.
I like these repairs! I always keep motors and a bunch of parts out of cassette decks. I was wondering whether you'd go down the resistor route, and I'm glad to see it and see that it works. Cheers!
When I needc to do this trick what worked for me is a 1W 3V zener in series or just 4 or 5 1N4007s in series. But this approach is good enugh since it is only for capstan drive, where the torque demand is pretty constant (asumming that no logic function is run from this point). For one motor units with RR and FW being so much hungry in current this will kill the power of the motor. Also, 9V system are 10 or more. This motors are TOLERANT by a nice marging. You can wide your seach on cheapo crappy 90s boomboex, the one with twin decks. Those are double speed motor (well external pot 2000 to 4000 RPM). Those are torqy, nice for logice decks that run ALL the functions capstan and FF RR from on motor, even for Kenwood KX500, 600 800 and so ... the worst decks ever made that require a 1HP motor to operate its clunky mechanism. I will stick to the JVC KD-X2 and so. This is how a bottom line deck is executed for low maintenance and longevity.
I saw a video on TH-cam yesterday and he said than you can order high quality replacement motors from Pacific Stereo in USA He said you can also buy new old stock Matsushita motors, but they take much longer to ship.
Nice fix :) That Fuji DR-I cassette looked very familiar, checked my cassette collection and I have two Fuji DR-I cassettes, but there's an X letter after the DR-I. Mine are at least 30 years old as I've marked 1991 for the year I've recorded some music from radio in one of them. Still sounds ok.
Opinion poll. As to junking the Sony deck? Once upon a time in 1980? I had a 20x20 foot bed room/office/recreation room. Replete with a modular stereo system, open reel and cassette decks and turntable. 41 years later? My room has shrunk to 8x12. My turntable's magnetic cartridge is fed through a RS premp into a Sony cassette deck, into my PC. Use the deck's volume for the turntable output as well as cassettes. Whether that Sony motor works or not? Makes a swell adjustable turntable output to the PC and Goldwave. Am I the only one who does this? EH?
Minisystems are all around, in their cheapes moment, especially the CD only or CD MP3. They are too new to be vintage and too old to be usable. With original speakers can make still a nice companion for the lab, but deck wont be missed. THis mechanisms are the last effort to keep the tape feature present on a minisystem. The later ones wont ever offer autoreverse, ultra lightweight flywheel, one motor for ALL the functions. Even if I took one of the oldest tape recorders like Philips EL3302, Im certain that W&F will do better. Bases on the weight of the flywheel and how the take up path have been decupled from it
Yamaha natural sound is nice sound equipment, NS stands for natural sound, the Yamaha NS-1000 speakers are very good :) Three-way. Fully adjustable mid and high. Beryllium in both tweeters and midrange makes it so exact that nothing compares, beryllium is better ressonance wise than titanium and perhaps anything else. Beryllium is toxic to make so perhaps the reason they quit doing them.. they did grow the membranes in plasma vapour chambers or something like that. Might be the best speakers ever produced. 12" inch paper woofers i think. They make new three-way ones today retro inspired of these ones, with ceramic speaker membranes i think in all of the elements, also 12" wooers. Called Yamaha NS-5000. Pricerange 15000 USD for a pair. If not liking the fully closed cabinet sound of both these models they also made totally open models called Yamaha NS-20 with very large polystyrene woofers, kind of facinating technology in them too, sounds more open than ever heard before :) If you ask me i think modern speakers has too much crossover components in them so they become too muddy, like king of average or something like that.. they may measure good on the test equipment regarding a flat frequency responce curve and people may look and ask for that.. and then the factories compete in making that becourse people want that flat looking curve.. but that comes with a price and the product end up average sounding regarding livelyhood music experience wise. Correct sound is not everything, i want lots of livelyness in them speakers too :) I have not heard any of these in real life, but i have read that these are good and i have a USB DAC and homemade headphones where i did buy many kinds of speaker elements and did after listening tests pick the ones with the strongest magnets i have ever seen on headphone speakers. The screws did stand spread in a magnetic 45 degree pattern on the magnets when i did put them there like i normally do, i has not experienced that in other headphone speaker magnets before :) They blow my Bose QC 15 away in sound quality, i did experiment with shell bass holes and speaker element holes and high frequency holes and dampening material so they became perfect :) It is the first time i did headphones, but i have made ordinary speakers since my youth 40 years ago. Some examples here. Of course TH-cam has compressed sound and all that, but one still can listen regarding the sound quality anyway in some degree.

Hey Dave just a thought perhaps the servo circuit board from the old motor may fit and work just fine with the replacement (basically gutting the old actual motor and using the original 12 volt servo circuit board.
@@12voltvids Okay thought the old 12 servo board might fit right on the undamaged motor terminals, it was just a thought. Did the 9 volter get excessively warm or hot?
@@darinb.3273 no heat whatsoever on the new motor. Running at 10.6v. remember 9 is the average. No tape deck used a regulated supply for the motor. So the voltage would fluctuate with incoming Ac.
@@12voltvids Ahhh I saw you solder it in with the normal wires from the original motor I must admit I did skip ahead so perhaps I missed where the placement of the 10 ohm resistor went LOL
Hi Dave, another nice repair job, you saved a nice tape deck from the scrap bin, and it sounds really good. I didn’t spot any continuity error, are you going to let us know?
There is one in there but I don't want to spoil the party. Think of an action movie where the hero drops his gun and in the next shot it is in his holster again. Now you know what to look for.
Hey @12voltvids have u tried to open up this motor!? I actually saved a DVD motor with just cleaning the motor. I guess this wasent possible i your case?
Cue the audiophiles as they try to explain that a 9v motor cant be used thanks to a resistor because the resistor adds noise and must have gold leads. Oh and was the motor from the Sony blessed by the pope?
@@Nairod2 it is a fact that publishing a new video too soon impacts the previous one. So I was letting the motor recovery from the donor unit gain some traction and generate hate mail by those upset i took a motor out of a perfectly functioning piece of shit to fix a good one.
@@12voltvids LOL .... the system is OK without the DECK ... who is using tapes on 20 years old minisystems ?. I mean, the cheapest deck possible. Take the transformer out and put the rest on the bin.

DON KILL THE SONYS !!!!! (LOL)
Ive got a Yamaha k30 cassette deck. It makes a really good recording for the car stereo (sony xr4800).
Nice tape deck! Never owned a yamaha tapedeck
I have a continuity error in here that was put in on purpose to see who spots it first.
I have a yamaha dolby s version of this seems to be a rare model and the remote to.
Nice job! Was it you would try without the resistor first? Thank you for the nice videos
I don't know. The belts just showed up. Good job. You could have used 4 diodes for the drop too.
@@markanderson350 5 would be a 3 volt drop, yes? Since the power supply source was 12.8 vdc. Resistor less complex.
@@zulumax1 it's 2.8 for 4. It's really not that critical.

Awesome job
Another tape deck to my growing collection.
ordered 2 12v Teac motors recently. made in 🇯🇵
Nice job Dave.
Good standard deck, they were just below high-end and not cheap.
This one is a great recorder. Sounds very similar to my Nak, better than the multiple 3 head Sony’s I have.
Great job as always
i would have scrapped the sony unit to save the yamaha deck. never had problems with those yamahas. they work hard and are reliable.

Wonder if a 9 volt voltage regulator would work.
Watch and learn
It have would have been a good idea to use an Lm7809 as its output would remain more stable than a resistor at higher temperatures.
@@tyronenelson9124 This regulators will top working if the differential is less than 3V, it is pretty tight.
@@38911bytefree Yes, according to the datasheet, the worst case dropout voltage is just over 3V.
