I have a Technics RS-M245X cassette deck which I purchased at Goodwill. It seemed to be playing cassettes well. However, I discovered that occasionally, about every minute or so, the speed would drop for a few seconds and then pick back up again. I assumed that seeing the capstan is more massive than it is for cheaper decks, that probably the drive belt was stretched. (I have a Technics turntable I got at a thrift shop that had that problem which was easily remedied by replacing the drive belt.) So I got a new belt, and using an online service manual and my ingenuity got it replaced. However, upon getting everything back together, now I find that the drive motor is dead. I thought maybe I had damaged something in the replacement process. However, there is voltage applied to the motor, but it doesn't turn. So that tells me that the problem is the motor itself. I thought maybe coincidentally, there was trouble with the belt AND the motor, which is possible. But my wife said, Well, maybe the trouble was the motor all along. And I thought, well maybe so. Maybe the voltage regulation circuitry was going out and then finally quite entirely. I read a thread somewhere where he had a similar motor whose regulation circuitry had burnt. He had just put in a resistive voltage drop, which sort of worked for him. So...
The motor is part number MMI-6A2LKPA. It looks as though Panasonic has had an equivalent part of number 330PPL3D9ONSD. It looks pretty grim trying to find one to buy online, at least at a reasonable price. So, here are my questions...
1. Where could I acquire this motor at a reasonable price?
2. Is it practical to rebuild the voltage regulation circuit for it? (I've worked a lot with voltage regulator circuits.)
3. Is there a broader issue that I'm not even asking?
Thanks
