Might: depending on the tube.

Ken,
I'm not sure if your original post was meant to be a tongue in cheek
way of disposing of a tube that had resisted all attempts to rejuvenate
it, but for those unfamiliar with tubes, be aware that making the grid
DC positive with respect to the filament or cathode virtually guarantees
destruction of the grid.
