I have done one by soldering extensions onto all 12 leads, that allows them to be guided into the CRT base's pins a whole lot easier. Again with less moving of leads, better visibility to guide them in.

Bob Anderson is an expert on such materials and recommended the silicone windshield repair goo. It is not hard when it sets, but allows very little movement.

Yup. I did it that way earlier today. I used high temp sensor safe silicone because I have used it before and it's held in opperation.
I siliconed the safety glass back on after confirming the base was on and soldered right.
The neck shot is the previous one I did since I can't photo the neck while it's in a bucket to allow the safety glass caulk to dry.
