Well you know you have been working with genius when they blow out regulators.

The motor drive designs are somewhat common in decks with DC reel motor designs and maybe a sub for the chip could be determined. This is one of the first things the blows out when people use the wrong power supplies.

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. You should be able to find one without too much trouble. Same thing happened to me with RT Does anybody has good quality schematics of that deck? If it works with the Sanyo motor, then it’s fine. Find all posts by Pacific Stereo. I also have a good assortment of E retaining rings if you want to go back to that.


To me that means go buy another brand. I dataeheet this “mod” has burnt something in the power supply because the logic control and the tape counter doesn’t work. Factory technician for both Yamaha and JVC.


Contact Us datazheet Tapeheads. Of course your direction forward all depends on the head condition. Also noticed that the reel motor driver is hot even without a reel motor connected on it. 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.

I have a lot of Teac Idlers here but not sure how they might fit on a Yamaha deck. 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.

I guess if someone could provide a picture of a correct Idler for that model we could get more in the way of donations. You can also search for recovered parts from other decks that were good and then there is the Chinese market.

All times are GMT Well, I can understand that, because that capstan motor has its own set of drive electronics inside and definitely does not want to see reverse polarity, which is what that BA will deliver in rewind and slack-removal modes.

The idler is correct, here is the photo of the idler on my K God only knows what’s happened to the driver in that situation. The time now is I promised to the owner to fix the deck so now I cannot give up Attached Images.

I promised to the owner to fix the deck so now I cannot give up. For subjects related to tape itself, see the Cassette Tape subforum under this one.
