Cassette unit does not play tapes.  When I operate cassette player w/o tape, the head unit rises, but only the right drive wheel section rises along with the head.  Left side drive wheel section remains lowered.  Of course I hope to fix at home and avoid heavy repair costs. Greatly appreciate suggestions for self repair.

I suggest that the drive belt(s) are u/s and need replacing.

Contact member Dillen who can supply

Graham - thanks for your reply. Would a slack drive belt cause the left side pinch roller to not rise when tape should play?

Thanks
