We used a belt from a VCR or CD player belt kit to fix the loading mechanism on a CED player recently. Had to clean off a lot of disintegrated rubber from the old belt. I think this is the only belt in it isn't it...seems like it is a direct drive turntable motor.
Here is a link to Studio Sound belt kits:

We have used their belt kits with good results.
They also sell individual belts.
