G'day JKuc
I have had exactly the same problem with my 9200. Plinius were great and exchanged my amp but i still have the same problem so it wasn't the amplifier.
I have noticed that my plasma tv which is plugged into the same power outlet makes my amp hum especially if the picture is bright ie lots of whites. Also my washing machine believe it or not as the motor starts and stops makes my amp hum in synch with the motor so i think its some sort of harmonics problem caused by the power supplies in the tv and washing machine.
I am concerned that this is causing my amp to run warmer than normal even at idle so i would also like to hear from anybody if they know what is causing this and if its doing any harm to my amplifier.
Thanks very much
