Hi Mike.
In the previous amp I owned, a Ameritron 80-B, it arrived at my doorstep
with the original Eimac 3-500z installed.
Power was a respectable 700w out, decided that there must be some more
rf horsepower in there somewhere purchased a RF part 3-550 tube. Power
was an instant 830-850 watts after that.
Fwiw, Eimac has not made a glass envelope tube since y2k
73 and such,
