There is just enough room in a Crown D75a to add a 120VAC DPDT relay next to the power switch. I desoldered the green and yellow wires from the output terminal board and ran them to the relay and back. I picked up 120V from the terminal strip in front of the amp. The relay drops out immediately on power down so you don't get the obnoxious noise or thump in the speakers.
