As an example, who is rebuilding CRTs now that Hawkeye closed???

Pretty much nobody, as far as anyone knows, unless you have a heavily modified DeLorean someplace.

At the risk of taking my own thread off topic, I really think the people who have been working with the rebuild equipment at ETF should practice on common B&W and color tubes first before worrying too much about pre war tubes and 15GP22s. Forget the metal cone stuff for now. Perhaps they have been, but all I hear about are attempts at rebuilding 15GP22s outside of that one monochrome tube that ended up with a 12V heater and one 21AXP22. Unfortunately their effort relies on volunteers at this point which limits the manpower available to learn and do the work and get to a point where those high value tubes can be reliably rebuilt at a reasonable price. Heck, I'd volunteer myself but I don't have the time or money to do it. I'm decades away from retirement and over a thousand miles away.

I seem to have found a CRT rebuilder out there, Thomas Electronics at: https://www.thomaselectronics.com/repair-overhaul/

Don't really know what they will charge but it would be worth looking into.

I know myself if I didn't have to work due to retirement and/or if I hit the powerball or something, I'd like to join the ETF CRT rebuilding project to be trained and learn the process. Maybe it could turn into a business to support ETF and VK member's projects and so forth, I don't know. CRT TV's are still desired by people who play videogames so maybe like record players in the last few years, maybe CRT's and/or rebuilding will make a small but significant comeback. Sorry to hijack the thread too but I've often thought about this during quiet moments from time to time. I do agree we need to start with more common and modern CRT's at first and then progress to the older ones. Just my $0.02
