And let's not forget the special edition Zippo lighters that a certain
beehive kicker whose name I won't mention (but his initials are Joe
Foley) was working on getting made for those who wanted to pursue this
approach. The hang up came in getting the R-390A front panel drawing
transferred into an etching on the lighter body, as I recall.

"No no, doctor - he's fine, really. You don't have any bees around
here, do you?"

I've had about the as much luck with the Zippo method as with jacking
up the heater voltage on the tube tester for a period of time.
Sometimes the gas goes away, emission increases, and other times
nothing happens. Always figured, what's to lose, if the tube is gonna
to be tossed anyhow? We learn by doing, as crazy as some of these
ideas may sound at first.
