I suspect that the initial flashing evaporates substantially ALL of the barium content, and reheating the getter is pretty pointless after that.
Once the getters look that bad, there is far more gas in the tube than even a full new getter would be able to handle anyway, much less whatever remnants you could hope to liberate by reflashing the old tabs. |
Theres a fellow on Youtube (glasslinger) that experiments with making his own tubes and he has videos where he salvaged getters from other tubes and re-flashed them in his own builds... so it should be possible.
