I stumbled on the World Pro Audio website today. Has anyone else seen this? He has an extensive mod to the PL400 (one originally assembled by our friend "Linda" at Phase Linear) Control Board and adding the White Oak Audio Bulk Capacitor Kit. I don't know if he realizes there is a new Control Board that would save him a lot of work. He charges $250 for this mod.
