CRT Rebuilding in Poland

Looks like you did well. Some of the rectangular color and other tubes here taper down to a smaller base lead seal button similarly...If there aren't arcing concerns between pins you might be able to get away with using those base lead buttons on some tubes.

I received information that there are still electron guns in the currently demolished cathode ray tube factory in Piaseczno. It's true that they are from color cathode ray tubes, but maybe they will be useful to me for tests and also for parts.
