Tape does not rewind at the
end of a track
Cause: Tape rewind is normally triggered by a 'pilot tone', which is automatically
recorded onto the tape before the tape rewinds. This audible tone sounds like a 'hum'. Should
normal operation fail, tape rewind will instead be triggered by an 'end-of-tape'
performing a 'manual rewind' by pressing and releasing the STOP button. There are several plug-in
relays under the main chassis. If these fail to operate correctly, the tape unit may malfunction
e.g. bulbs won't light up; tape unit won't record.
