I have a darn I forget the model (R-86?), but it has a 6-08870-06 CCC with a very odd problem.  After fixing up some battery corrosion, it would power up and play whatever selection it had stopped at, then when that cancels, it proceeds to play both sides of every record.  The only way to stop it is to press the "clear selection memory" button.  At first I didn't have a battery in it and thought maybe on power up one of the two 5101 rams are getting *confused*.  I added a battery and it seemed to have cured the problem.  Then yesterday it started doing it again.  I do have a small quantity of 5101's in stock.

Thanks,

Tony
