Turntable speed problems...


I had to re-set up my turntable after replacing my phono cables and phono cables and I encountered a problem which borders on the bizarre and was wondering if anyone has experienced it or something similiar to it.

About 5 minutes into playing a record, the speed of the turntable "jumps" appreciabley faster (my turntable is a SOTA star). It is extremely anoying for only that time when the speed changes. After the speed changes, my ear becomes used to the newer speed, and my teeth stop grinding.

Has anyone encountered something like this? I suppose a fly-wheel might be on order (to regulate the speed), but why am I having this problem now when I have owned the turntable for 14 years and never experienced a problem until now? I still run the SOTA into a Trip-lite (just like before)

Thanks for your help.

I agree to Theo. Have the same problem with my Transrotor Electronic. In this case it very likely is some elctronic part in the speed adjustment section.
Maybe it's an excuse for a new TT :-)
Sounds to me like motor failure, I would guess that soon you will turn it on get nothing. The fact that you moved it or re-connected it is just coincendental. Start looking for a motor, I had Pioneer PL540 starting to do that and that was the perfect excuse for a new turntable.
