What I am going to say is a cliche, but I would like to emphasize once again that replacing an electron gun in a CRT is a very difficult task. New cathodes are needed that no one produces. The workshop I wrote about has such elements and different types with pumping tubes. It is probably a phenomenon on a global scale. As a result, it is possible to regenerate various types of picture tubes irrespective of their electrical structure. Melting glass takes a lot of skill, and I don't think anyone will get it right with a CRT after a few tries in the garage. I think that the only thing that is unlikely to be a problem today is to create a vacuum. According to the original method, the picture tube had to be heated to about 400 degrees during pumping. Today, this stage can be omitted by using better-quality pumps, e.g. turbomolecular pumps. Of course, the final product must be safe. It can't break in your hands.
I am eager to join the project of regenerating a damaged pre-war picture tube. Unfortunately, I do not have one, and no one sells such old CRT on well-known auction sites.
