Re: CRT rebuilding
Many of the rebuild shops also recoated the phosphor so you got a new gun assembly and new phosphor. Obviously, results depended on the skill and quality control of the rebuild shop. Thomas was one of the better ones. I recall getting a rebuilt monochrome TV tube that had hand smears in the phosphor coating of the screen. It still worked fine but we sent it back because it looked horrible when off.toggle quoted messageShow quoted text

I remember seeing re-built tubes back in the day. You could see the scar
where the new gun and glass assembly was welded (melted glass) on the
neck of the CRT. If I recollect correctly, and I doubt I do, I think we
could buy rebuilt CRTs for maybe half the price of a new CRT and they were
just as good as new (only the glass was re-used) if they knew how to
align the guns.
