I took a Dual 1219 that used to work decently out of my storage area, it hasn't been used for about two years and now it refuses to stop. Either by activating the "Stop" lever or automatically at the end of a record, the arm goes up, returns to the armrest, goes down, then when you'd expect the sound of the switch-off, the arm goes back up, moves to the center of the platter, returns to the armrest, etc., etc.
Only by holding the arm when it's on it's rest is the motor switched off.
After getting the turntable out of the plinth, the stop function has worked a few times correctly, but after that the odd behavior was back
Shaking the TT a few times hasn't helped, either...
As far as I can see, the "Steuerpimpel" (which is often the cause for misbehavior) looks OK, the other functions do work all right, though I haven't tried to change records (not really interested).
Anyone a good idea on what's behind the behavior? The service manual doesn't mention this kind of situation...
Thanks for any hint!
