Technics RS-TR255 Cassette Decks

This may well qualify as a "Lost Cause", but ...
I have 2 dual decks per the subject line. On both, the record drive will
not spin a (good, tested) tape. Same tape works OK in the play-only
drive.
On a workbench with the case open, I push button for play or record or
rewind (forward or backward), the machine appears to do a check for
end-of-tape, clicks, and stops.
I disconnected a motor thinking it might be frozen: it was not.
The behavior it exhibits is identical to what the device is supposed
to do when I, say, tell it to play a tape that is pre-positioned to
end-of-tape. I'm guessing that the problem is with the end-of-tape
sensor.
I am neither expert nor helpless with electronics.
Any hope for repairing such a beast?
TIA,
Puddin'

Usually the take up reel has a sensor to see if it is spinning. The sensor
typically might be a magnetic switch, a simple switch, or an optical sensor.
Sometimes these sensors are driven by belt connected to the take up spool.
There could also be a function built in to activate a stop mode when the
tape counter hits zero. This is so you can rewind back to the same spot on
the tape.
