Hello
I have a ADC linear tracking automatic turntable LT32. I ordered a new belt, placed a record on it, turned it on and its turning too fast!
I recently moved, so the move could have damaged it. But I hadn't used the turntable for months so I don't know when it went from normal to Chipmunk speed.
Both speeds, 33 and 44 play extra fast.

Is there anything i can do or check for?

Thank you

I don't see any service info out there on it...but it may have speed adjustment pots on the motor if it's a DC one.

I bet it's running "open-loop," with no speed feedback. That can happen if the speed control switch is broken or has a bad connection. It can also happen for reasons much more difficult to find and fix.

i need to open it up to see if i see the speed adjustment pots. I've seen pictures elsewhere of another ADC LT model that does have the pot and the poster was able to fix the speed with that adjustment.
Just need to find time.
