Don, you have described the problem on my unit to a tee. "Cassette ''B''
assy
would lock up intermittently. Sometimes you could not even open the
door." My customer even complained about the CD not working also,
although I haven't seen it act up while working on the unit. I did clean
the cd mech and motors.
I have gone ahead and changed the 2 cassette drive belts as Ed
suggested. I used SBS 10.0 from Global. They are just slightly shorter
than the original belts in the unit.
After installing the belts, I played with the cassette operation,
switching from deck A to B, back and forth, plus changing direction of
play. Also rewound tape to beginning, etc. I haven't declared it
repaired yet (Ed will get a hoot out of that comment) but I am thinking
that the belts were the cause of the lock up. I didn't suspect the belts
because they seemed to be snug enough, not loose.
