Rca ctc-5h

[EdKozk2]

Today I reached the point of testing the 21AXP22 crt with the recapped CTC 5 chassis. As many of you suspected, the crt is a useless gassy dud. It produced pretty swirling colors of pink and purple along with a few sparks in the neck.
I have a 21FJP22-a from an old Zenith set. I was going to try this crt with the ctc5 . That way I could test out the deflection and high voltage circuits.
Has any one used a newer crt in a ctc5? If you did, did you reuse the original plastic crt cover and yoke assembly? Can I remove the 21FJP22's current banding and mounts to fit the crt into the ctc5's mask?
