I have a problem with one TK50 that the connector between the motors
and one of the PCBs is flaky. It will load tapes sometimes, but
eventually, the tape goes slack in the drive and won't rewind. I've
fiddled with it enough that the next time I need to use this particular
unit, I'm going to take Allison's advice and solder the motors to the
board.

I would remove the covers and see what state the tape is in. It might be
half-in, half-out, it might be stuck on the leader, indicating a problem
with the optical interrupters as mentioned before. Also, when you get the
tape out, finally, inspect the barb at the end of the takeup leader in the
drive (not the cassette). If it is crimped, you'll get unreliable loading.
If it's missing, you won't get *any* loading.
