I thought something was wrong with the tester so tried another tube, and it was fine. So, I hooked the tester up again and, one by one, I watched the filaments burn out. The crt had gone to air over the course of 10 years.
I have one of those RCA test jig tubes with "Test Tube" etched on the face. It's a non-bonded 21" round color. I sure wish the etching wasn't there. I have heard others say it could be buffed out, but I don't know if I'll ever try it. The man I got it from had the jig a short while when he happened across a great deal on a then late model set with a broken crt, so he swapped this tube in and used it as his main home tv. Eventually he saved up for a new tube and put this one back in the jig.

It can be polished out as with scratches that are not deep. Julian
