So the 6/6 regeneration project still makes sense. I wonder if the deterioration in the functioning of the 6/6 CRT and similar results from the gradual loss of vacuum or cathode wear? This may have an impact on the scenario of rebuilding the picture tube. I am thinking very seriously about this project. At the moment I have collected about 200 picture tubes manufactured until the 60s. I estimate that 70-80% are functional. I have about 120 new electron guns and one pumping system with a turbomolecular pump. A jeweler's welder is on the way to work on the electron gun. Now I have to find some time. And this is probably the worst thing about all this. My goal is to regenerate the picture tube, not to recreate the regeneration process. I assume the use of new technologies that were not available in the past. I will never gain the experience that people who dealt with this issue had long ago. Any information on this subject is very valuable. The project will include several stages: removing the vacuum and restoring the vacuum in a working CRT, replacing the electron gun, replacing the parts of the gun. Unfortunately, today old CRTs have museum value. Using them for experiments with the risk of damage is very controversial. If the CRT is part of a TV set, it should definitely stay in it. However, if the CRT is in a closet, it can ..........
It is interesting that some old sets did not require a video amplifier. I suppose that replacing the heater/cathode system in an old CRT with a slightly newer one should not affect the operation of the entire system.
