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.
