   If the Yamaha were actually producing hum, this would indicate most likely a   
   power supply problem.   
   Normally the Yamaha's protection circuit would shut it down in this   
   scenario.   
      
   Does the problem with ONLY the speakers and no other devices hooked up?   
      
   If not, perhaps a ground loop. This is not uncommon.   
      
   If so, maybe a main power supply capacitor open circuit - I'm not sure if   
   that would trigger the protect circuit.
