I will keep you in mind for sure. When ready, I will make announcement here. Mom never said any such thing.
My friend Paul Ruby took that shot. It turned out quite well. Me and the GU80. That is a 450 Watt plate, true pentode with a thoriated tungsten cathode taking 12V at 12A. I think I will do ultra-sonic heaters. There is a chap in Ann Arbor that has some experience with those supplies and he'd help( and try to keep me from killing myself with a 1kV/1A power supply ).
cheers,
Douglas
