The first step is to disconnect everything from the amp except the speakers and to power down everything except the amp. If the hum goes away you may have a complicated problem to diagnose. If the hum persists then you know it is in the amp.
You didn't say if the hum was in one channel or two channels. This may provide a clue to someone who knows the circuit diagram of the amplifier and/or has had similar experience.
