[R-390] 3TF7 Ballast Tubes

[James A. (Andy) Moorer]

  Hmm. In the spirit of the re-stuffed capacitor cans, maybe we could 
find some similar-looking dead ballast tubes, carefully hollow them out 
and put a nice, shiny resistor in it & seal it back up. I believe they 
use soft glass for tubes, so a good jeweler's torch should do the trick.
