[R-390] OA2 replacement

[Bill Hawkins]

Um, if the VR tube is dark because it's lost radioactivity,
all you need to do is supply ionizing radiation from an
external source to get it lighted.

Find an old dental X-ray outfit and zap the radio with it
after you turn it on. The lead apron is optional at our age.

Gee Gord, I suppose this means I can't snort the gasses from a  
voltage reg tube as a dessert after licking a radium meter face. I'm  
quite disappointed.

damp sheep)
