I 100% agree with this. But if the tube were mine and I had an RF generator, and a getter "wand" I would try it.

I would too. I just wouldn't have my hopes up. On the other hand, I have seen a number of vacuum tubes where it looked like they barely flashed the getter and there might be much left.
Your comments about the 6CB5 are encouraging. I'll have to try it. I can evacuate the 6J6 without needing to bother with the getter and I can RF heat the elements to outgas them.

I can't run that fast, anymore.

I guess it would depend on whether the seller would understand well enough what you were doing. The value of the set would be greatly enhanced with a good 15GP22 and I would hope they would let me test it and understand if the result was a briefly glowling filament. Otherwise I'd be reluctant to pay top dollar not knowing if it was good or not.
The Tesla coil vacuum tester that I have would probably scare them if they had never seen one before.
Of course since I'm not actively searching for one, it's easy for me to say. Maybe I'd be of a different opinion if I were about to make an offer for one.
