Rebuilt 15GP22's?

No way, I'm afraid at this time. There have been many attempts to rebuild 15GP22s, and all have been unsuccessful. As was explained to me several years ago by Gino at MetroColor, the metal flange on the 15G will separate from the bell of the tube as soon as they try to heat it. They tried, with donor 15Gs from Ed Reitan, Gary Miller, and myself. And back in the late 80s, Gary Hough and I tried an experimental rebuild with Dunbar. We couldn't get the 15G gun, but we had two tubes that still had filament continuity re-evacuated. They lasted about a month. The best explanation of "why not?" came from the guys at MetroColor, who have been there since the 50s, and held government contracts and met all ISO guidelines. In other words, they know their tubes. To rebuild the tube, the oven will have to be modified to heat at a precise rate and at a precise temp. There are also many other problems.

Bottom line, be skeptical of anyone who claims they can do it. UNLESS it is one of the women who worked on the original assembly line for the 15GP22, LOL...
