It's definitely not normal hum. It's more like very low frequency thumping that causes the woofer to bottom out. If I so much as touch a knob on the front panel, there's extremely loud scratching for several seconds and the woofer really goes crazy. I'm afraid to hook the speakers back up to it for fear of frying them.
