Yep, I had already started to collect bits and pieces to build an analog power supply, very simple one comprising suitable transformer, bridge rectifier, caps, zener and a couple of transistors to eliminate this possible source of interference. I had everything on hand except the correct size DC power socket. The audio is fed to the amp using plain RCA stereo leads.
