I have a Sony Betamax SL-HF750 with a problem. This is the model where
the tape loader is in a drawer that skates out like a CD player does.
The wormdrive motor starts and stops so the drawer wont come open. No
foreign objects or broken parts visible under the hood. Any clues for
how to fix it? My tech and I are baffled.

I had one of these with the same problem many years ago. I gave up on it and
the customer wound up sending into Sony for repair. I think Sony replaced
the entire mechanism. As with any mechanical problem, you have to get a
clear view of the moving parts. With the unit unplugged, try putting a few
volts dc on the wormdrive motor and take note of where it jams. Then you
need to disassemble the mechanism until you can see where it is hanging.
That may involve removing much of the mechanism as I recall. You should also
consider that there is a good chance that any gear, arm, or other part will
no longer be available.

Good luck.
