A couple of other questions:
If I were to connect filament voltage ONLY to some tubes that have been
in stroage for a long time, would it be okay to do so without proper air
flow around the tubes? In other words, is the heat generated by the
filaments alone enough to damage the seals without proper air flow?
And, since running filaments at or slightly below nominal voltage saves
filament life, could I "clean out the gas" in a shelved tube effectively
with a filament voltage substantially lower than the specified voltage?
