Apply a very fast 12VDC between the grid and filament pins.
Ive had a better than .500 batting average with tubes that werent gassy to
start with.

No I can't see that. The tube "looks like" an EIMAC but not sure about
that. Lettering gone.

Does anyone have a restoration technique to remove a grid cathode short

I have on just laying here---don't know why I keep it. Filament still
lights. No plate to anything short.
Can you make out which grid wire or which side of the grid basket is
touching the cathode or filament?
Carl can tell us if restoration is possible.
