CTC-4 Director 21

That set has so many major problems that the LEAST of your worries should be the condition of the CRT. Replacing the CRT is not going to be some magical cure for your issues. Put it on a tester if you like, but even a good tube would produce a terrible picture when driven by that chassis.

I didn't believe it would be a magical cure, but the red gun tests really weird and I thought that it might be a pretty weak gun and in result colors that use red would be either not present or incorrectly colored. This set is a real pain so far. But I'm going to just start with a fresh brand new set of tubes and go from there. Something tells me I will probably be doing some alignments . The red gun on the CRT tests good at first but then 1 second later the needle swings pretty erratically but the swinging stay within the ? And good range. Both other guns do this but not nearly as much. And I've found also that the red screen control does almost nothing too, I'll have to check it.
