I have a Sanyo SuperBeta VCR-7250.

When I put a tape in, the tape completes its "expansion" around that tape
path, but never quite gets tights and the tape mechanism shuts down.

I understand that the 2 likely suspects are the idler wheel and the reel
sensors. I cleaned the idler wheel with no change and I have no idea where
to find reel sensors.. .if this model even has them.

Any suggestions and/or corrections?? Thanks,

Lar
