FaultSolution
Tape remainingOn a few units, this was sometimes found to be rather inaccurate, often saying there is half a tape left and suddenly giving a warning the tapes end is imminent.
Tape remaining display issueThis was probably down to dirt and debris surrounding the sensor.
Although i have yet to see one with this fault.
No control of tracking in either normal, slow motion mode or both.The tracking control potentiometer fails internally causing there to be no centre contact of the metal slider on the resistive carbon arc. The small plastic pins holding the centre contact break.

Thus the machine is at the fully open or highest resistance position which is hard to one end of the adjustment range.

It is possible to disassemble the unit and super glue the contact back in place. Alternatively you may have to adapt another design of potentiometer to perform the tracking function.
