Sony Betamax SL-2300 Capstan Speed Problem

have a Sony SL-2300 Betamax vcr that is having trouble with the capstan
motor speed.
The picture gets tracking lines in the picture about every 2 seconds. It
clears up and the the
tracking lines come back. Also the sound has a warble.
I know this model Sony Betamax had a problem with the capstan motor servo
lock
but don't know how to fix it. Any help would be greatly appreciated! Thanks!

First thing, replace the rubber pinch roller.

The tracking potentiometer develops an open center-tap. Common problem.

Mark Z.
 
Thanks for the responses on this thread.

The pinch roller is not slick and is pulling the tape through smoothly
and evenly.
The tracking control has no effect on the picture tracking. So it
sounds like Mark's tip about the tracking potentiometer might be the
problem.

I removed the tracking potentiometer and cleaned the contacts as best I
could.
I did not see anything else wrong. But I am not sure what I am looking for.

Cleaning it did not seem to help. Am I doing something wrong?

Also I think the tracking potentiometer is no longer available from Sony.
Is there a sub that will work? Or is it time to chuck this unit?
Thanks!
