Pioneer a-501R
The amp lights up, turns on and then the resistor clicks in well, but there is no sound at all.(just a barely audible hum from the speakers) All the controls appear to function well - Any troubleshooting clues for this model? BTW, There is a whirring sound from within the unit? Thanks in anticipation Phil
