Recently I pulled some old vinyl from storage and discovered my cheap Emerson
stereo I bought in the 1980's would play them slowly, like the the belt was
dragging. Anyways, after a little searching it appears that it is common for
the rubber belts from that era to break down and turn to sticky mush, and
another issue with older audio equipment was small plastic gears losing
teeth, or completely disintegrating due to age or chemical composition of the
plastics.
Another observation with just about any electronic vintage device is there's
quite a few bad of leaky capacitors out there. Some are in such bad shape
they are corroding the traces on the circuit boards. I'm sure you ran into
similar problems, but I felt like venting on how it makes collecting old
items a bit of a challenge.
