Bob, Thanks, that looks just about perfect. Solid state, true sinusoid 3 phase, 30A continuous but can do 140A for 4 seconds - seems made to power a big bunch of vacuum column tapes.

I also have a small Phoenix rotary phase converter, also from ebay. This one seems to have unbalanced outputs. I believe it is for motor loads only. Bob
