Eli's.correct. The getter flash material once initially flashed cannot be reflashed.

However i have had great success with baking out gassy tubes to activate the getter flash without voltage being applied.
I believe getters get heated in operation, and are supposed to absorb stray gases, the voltage maybe ionizing them. Heating externally will activate getter flash and do a better job in my experience.

I use a toaster oven set at minimum and raise temp 50 degrees F every 30 minutes to 300 degrees and hold for several hours. When done I unplug toaster and allow to drop to room.temperature.
