Hi Fellow contesters.
A month or so ago I blew a tube in the FL-2100B. I finally got it
opened up yesterday, (Wed), to check things out and found one of the
Svetlana 572-B's had a filament to grid short. It really sparked pretty
when I turned the amp on. Anyway, not wanting to wait too long for a
replacment, I stuck in a Penta Labs tube I had here to see what would
happen. I turned it on and tuned it up and got 600 watts out on 20 with
1 Svetlana tube and 1 PL tube. Now next contest I can use the amp again.
So much for "mixed pairs" at extra cost I guess. 73
