So very disappointing, I would have thought even with badly worn playback head would have got at least some sound. The tape I tried I think came with the unit so first need to make sure there are recordings on the tape.
From this I found that the switch for switching off the loudspeaker and switching in 5 ohm resistor dummy load is ganged to the potentiometer on the right hand side of the unit, I assume this may be the record level pot.

Even with a blank tape you should get audible tape hiss. Have you tried touching the connections to the replay head with volume turned high when in replay mode? Should produce a very loud hum.
