For those who weren't around then: As I remember the thread, if you held
your Zippo lighter against the silvered part of a tube to heat up the
gettering layer inside the tube, it would improve the performance of an
old, tired, and gassy tube.
Me, I never tried it.
I did make an old type 27 a bunch worse by over heating the filament for a
while. That's supposed to work for thoriated tungsten filaments as found
in transmitting tubes. And WD-11's. Good luck!
Oh, the string to keep the spring nearby when it goes SPROING is a nice
idea. I've used it back when I worked on clocks and watches.
