Had the same problem & checked around on the net. Several people tried replacing the belt, but it had no effect. Spoke w/ several repair shops around the country and they concur with what I'd read on the net - bad motors. 3 or 4 repair/supply shops told me getting a motor would be impossible. Since I only listen to 33-1/3 LP's, I messed around w/ it a little and found a solution. Take the turntable out of the unit & you will find a small circuit board attached to the bottom. On that board is a small square blue fixture w/ a white circular "dial" in the middle (has grooves to accept a small straight blade or a phillips screw driver). This controls the voltage to the motor, which in turn controls the motor RPM's. If you set the selector switch to 78, you can experiment /w turning that white circular "dial" to slow the motor down. It isn't very hard to get the speed set properly. The down side is that you will only be able to play 33-1/3 LP's, but they are probably the most common anyways. I assume you could do the same to set the speed for a 45, rather than a 33-1/3. Down side is that you will only be able to play 1 size LP on the 78 speed setting, but it's an easy adjustment that can keep an otherwise in-op turntable functioning. Good luck!
A like problem was brought into my shop. Your turntable presumably uses a rubber belt to drive the platter. Assuming the belt still has sufficient tension to turn the platter, the culprit is most likely the motor itself. Since the motor still does run, albeit incorrectly, the speed switch and related circuitry appears to be intact. Replacing the motor is not a major operation. Finding a motor seems to be the real challenge. I'm still searching.
Problem is the motor. Inside motor are 2 potentiometers. each 1.5Kohms. They open up. If your fairly handy and patient, you can replace these. Once replaced everything works correctly.
THIS IS== DOCTOR FIX IT==
THE TURNTABLE THAT TURNS AROUND, HAS A CLIP THAT HOLDS THE TURNTABLE ON TOP OF YOUR MECH. IT IS AROUND THE CENTER WHERE THE SHAFT COMES OUT THE CENTER OF THE SPINNING TABLE.. GO DOWN THAT SHAFT ABOUT 1/2 INCH, TAKE A SGREW DRIVER, AND REMOVE THAT CLIP. LIFT THAT TABLE UP, OFF THE MECHANISM.
THERE IS A ROUND DRIVE WHEEL (ABOUT 2 INCHES) MADE OF RUBBER. CAN YOU RUN YOUR FINGER NAIL INTO THAT DRIVE WHEEL (YES ) OR (NO).
IF IT IS HARD AS A ROCK, THAT RUBBER DRIVE IS YOUR PROBLEM.
I SELL , AND INSTALL RUBBER FOR DRIVE WHEELS . COST INCLUDING SHIPPING IS $39. IF THAT DRIVE WHEEL HAS OIL ON IT.
GET , AND CLEAN WITH ==DENATURED ALCOHOL.==

I took it apart and the belt was off where it needed to be

Pjam,
