Is the red gun filament out or is the emmision gone?
Has the tube been rejuvenated?
I am probably hoping for too much but I just thought if a filament was out that I may be able to tap and get it to work. Perhaps you tried that. I have one that had one filament out and tons of tapping made it work again. I had the filament voltage up high and allowed a slow cool down of 1/2 voltage for a half hour then 2 volts, then 1 volt for a long time and it seemed to make it so they come on now without tapping.
Also, I wonder if you have a shipping carton for it?
Thank you,
Johnny
