?   Even for a gassy tetrode with handles, I have never found one that
would magikly get mo' betta by operating the filament.  The bottom-line
seems to be:  if there's gas, you'd better pass.  However, if there's a
leaky ceramic-metal seal, Econco can resolder it during the rebuilding
process.  It is my opinion that Ham radio is not free from old wives'
tales.
