Wake up Maggie...
OK, I went through a box of alcohol wipes and cleaned the hell out of those rollers, the turntable, and the motor spindle. I found out why the record changer wasn't working. Besides the wheel being slippery, it wasn't aligned just right on the 33rpm spindle.
NOW it plays like a Magnavox should. The turntable jumps right into action, the reject mechanism springs to life when it's needed without slowing down, and the finishing touch is the gentle and perfect needle drop right in the lead-in groove of the record. A great difference between that first video where she struggled to get the first note of "Beat It" right and that clumsy jerky record change. And the music even sounds better without slight pitch fluctuations.
So again, Thank you RickR for helping me get Maggie on her feet again. She's in a good home and she will live a sweet, happy life playing music for me and Helen when we do our wash. Yes! Her home is the laundry room, of course.
