I could have sworn at one time I heard you say that running too little voltage
filaments was just as bad as running too much, in the mode of preserving the
expectancy of the tube in question.
Don't get me wrong, I don't want to start an argument - indeed, I'm all for
getting back to the technical discussions of Amateur Radio, and let someone
else deal with the politics, thereof.
