The cat always is interested in things we're working on!
I tried re-flowing the solder on the pins of the CRT but no luck. The weird thing is, is that it did show some emission for a few seconds several times when the tester was first connected and I turned the filament voltage up to 9 volts. When the filament voltage was kept at 6.3, no emission. This only occured 2 or 3 times when the CRT tester was turned on after leaving it off several minutes. After these few times, it never showed emission again, and when it did it was only for a few seconds. I maybe better check my tester again with a known good CRT but it seemed to give legitimate readings on some color CRT's several months ago. The filament on the DuMont CRT is still working but still no emission.
