Nice of you bigred. :thumbsup:
I just searched my schematics and unfortunatly didn't find it.
In my opinion, we are here to help eachother, and not to take care of commercial interests.

best regards

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
