Hmmm. Indeed I must be remembering it wrong. The SB-200 used a pair of
572B's I think, and I see from my triode table that the 572B is typically
run at 2400 volts, so I guess it wasn't that old SB-200 after all. I have a
strong recollection that it was 600 volts, so maybe it was some other amp or
an old tube transceiver I was working on. Can anybody think of a common ham
PA or final that would have run at 600 volts on the plate? I don't think it
was 2400 volts because I told a friend about it and he said he once touched
3000 volts! It threw him clear across the room and slammed him into the
wall. Another ham lucky to be alive. A possibility is that the HV fried so
many of my brain cells that I'm dividing the voltage by four...
