Congrats Bob, John and Scotty!
I've had little interest in the 15GP22 since it had electrostatic convergence and dynamic focus while my 21CT55 had magnetic convergence and static focus. Resteming the 15s seemed to be the last big problem, finding a stem supplier that produces a glass compatible with the original bell glass without cracking, right?
But I still don't know how you obtained the new gun assemblies. Assuming no original guns are available you couldn't use 21in guns since they were magnetic converged. I don't suppose you cutoff the 21's mag convergence pole pieces and attached a simulated electrostatic grid #4 collar to perform the convergence function? Its certainly unrealistic to clone the originals from raw stock. Could you have tediously remove the 3 cathodes with heaters from the original dud and replaced them from new 21in guns.....naw, forget it.
So how did you get perfect replacement gun assemblies for your 15GP22 rebuilds ??? Tom
