Default Crinkly tube getter Is this bad?

I bought this tube and the getter is kinda flaking off. The tube tests good and the getter is still silver. Did something cause this or was it made that way? Will this cause the tube to fail or die early?

I've seen this before. I'm not sure why this happens except to think that the inside of the glass may not have been as clean as it could have been. But as long as you keep any flakes at the bottom, you should be OK. I doubt it will shorten the life of the tube.

Thanks, that is good to hear. Now I just have to figure out where to get another engraved base 50 for 20 bucks to go with it.

Holy mackerel! A 50 for 20 bucks! I'm jealous. Better face Mecca and bow deeply for finding that one.

I have a vintage 45 that's like this. When it is not shorting, it works fine and tests strong. I'm weary about using it because there is getter all over the glass base of the internal support structure where all the wires come out.

In my old thread, someone mentioned something about dealers trying to re-fire getters to make gassy tubes test good and this can be the result. Not sure how true it is.

20 bucks? Seems kind of steep to me. I just picked up a globe shaped Cunningham CX350 at the local antique shop for $5.

Default More Getter flash flakingoff

I'm bumping this thread to see if there are any more answers.

I've purchased a few like the one shown in the attached photo.

They test OK and seem fine.

I doubt it is from anyone trying to refire the getter, as I've seen too many different types from different sources listed on ebay.

The only tubes I've seen it on are old ones with the silver getter. I've not seen examples of newer tubes that have the black getter flash.
