Folks:
I have a very old but healthy Drake L4B with the gray solid carbon plates, with
flutes oriented horizontally. I also have used, more often, the 3-500Z amps
with the tantalum plates, with vertical flutes. Do both kinds of 3-500Z have
the same kind of gettering, degassing process, in which, by heating the plate
(the tantalum plates to show much red color) and less so the carbon
plates...you burn off residual or leaked gas contamination inside the envelope?
Best Regards,
73, de Pat Barthelow AA6EG
