Back to the original problem.
The belts had dropped off, obviously perished.
Now , sometimes, on using the power take off to slide up the head


both new bands and cleaned pulleys. moving from REW to play causes the band
to fall off, presumably due to a snatching / breaking / imbalance associated
with this double connection to the tape presumably at take up.
If I put in a guide then it can't fall off and will presumably self centre
back up the vague hump on the periphery of the "reverse" flywheel.
On baluster/ bulbous motor pulleys they usually have a preventer disc either
side of the bulging active part. This pulley has a larger pulley on one side
but nothing on the other in the way of a preventer.

Hmmm....if thers no sign of there having being a preventer in the
past, i'd be inclined to think that the belt is not the correct
replacement - too slack?? It should be albe to withstand the change
of tension without slipping or wandering.
