So far my experience with a company Hexunda was very bad but not all companies over there are up to no good. Contact Us – Tapeheads.

The idler is correct, here is the photo of the idler on my K If it works with the Sanyo motor, then it’s fine.

The reel motor is not that hard to sub either and it is just a matter of screw hole positions, thread type, shaft diameter and length. This is also the 3 V speaker amp source as well. But you will need to see why the supply voltages are out of whack. Find all posts by Yam Same thing happened to me with RT Pacific Stereo store manager, service manager, Central Service lead tech, liquidator at our demise and owner of what’s left.

Very special and not made in any other IC that I know of. There is the sm on Electrotanya but the schematics are unreadable and some pages are missing. Here is the pics of the motor: Does anybody has good quality schematics of that deck?


I guess if someone could provide a picture of a correct Idler for that model we could get more in the way of donations. The EG motor is not the bad choice as these motors are the only stock solutions to the motors that are burned up or worn out. I also have a good assortment of E retaining rings if you want to go back to that. Hi, I received a new Mabuchi RFTB motor ordered in England, when replacing the reel motor I took the opportunity to clean the idler tire but it has also been modified -First as you can see the “Jesus” clip was lost and replaced by a piece of plastic.

Hi, just received and replaced the BA, it works fine, now I need to put a new reel motor and make some adjustments of the recording circuitry left channel 1dB off. You should be able to find one without too much trouble. I have a lot of Teac Idlers here but not sure how they might fit on a Yamaha deck.

Oh, I forgot to mention- now you see why I like paper manuals- go to stereomanuals. The power supply issues just means the zener diode if discrete has been blown out or that the regulation transistor is shorted- probably by working on the soldering with the power on- real idiots worked on this.

What would be very difficult to deal with is if the capstan motor drive IC is bad. Hi and thanks guys, just discovered that the thread was replied.

IF it is worn out then your deck for whatever is left might datadheet a donor deck for parts. Firs order of business is get voltages back to where they need to be, then start looking for the parts to get the deck working again. The DD motor works fine, the problem is on the reel motor and his driver circuit.

For subjects related to tape itself, see the Cassette Tape subforum under this one. You need to put a correct reel motor where it belongs and probably replace that BA Pacific Stereo Sendust for brains. I promised to the owner to fix the deck so now I cannot give up Attached Images.

The biggest problem with Yamaha deck is that you can get any parts for them and Yamaha like Sony does not care to even deal with it- they want to sell you a new item. God only knows what’s happened to the driver in that situation.

Cassette All discussions pertaining to cassette decks. This one can be used in the Teac A This is one of the first things the blows out when people use the wrong power supplies. If it does not, it’s probably not fine.
