Thanks for all the great info on amps and tubes. I found the Eimac and Svetlana sites (there seems to be a lot of cute gymnasts named Svetlana). Eimac gives more structural details on their tubes where Svetlana give only external specs. A lot to digest. I better start thinking about running that 240VAC line, or maybe move the shack into the laundry room and use the clothes drier outlet. HI! Lou W7dzn
