Excellent! I knew that the gettering absorbed gasses and was flashed / activated inside the tube to do just that.
What I didn't know, was what the metal "getter" structures did. We use that structure =the getter= all the time to describe tubes . What they do after activation is....nothing... That is incredible to me but completely believable. They hold the Barium flashing material while the tube is constructed then shoots its load when flashed and just sits there for the rest of its life. The gettering/flashing in my moderately sized tube collection varies widely. I have a bunch of Sylvania 6SN7 Ws with so much in some cases you can barely make out the rest of the structures, and some very well used Marconi ECC82 tubes whose faint brown gettering is a thin 1/2 inch circle at most.
Thanks for explaining what the getter structure does, that was exactly what I wanted to know.
Have any of you noticed that the flashing on the bottom of some tubes seems like it is less than that of a top tube flash? It may just look like that and not really be less.
