After testing one of the CRTs, 10FP4, I noticed that I could see a very faint color of purple in the back of the neck.Could someone tell me what that means? Everything from the tester checked out. The test results on the B+K 467: Good filament, good life, good emissions, and good tracking.

Thanks for the answers

As was discussed on Videokarma: A glow on the glass may be OK, but ultimately wait until you get the tube back into a working chassis to confirm.
