Agreed, but no one is willing to sell...
I predict everyone with a round tube in general, color or B&W, will become increasingly hoardish in the coming years. The CRT's days are numbered, and the supply of good jugs is drying up. Add to that the fact that the last (reputable) rebuilders are closing their doors forever, and you can see that the future looks bleak for this hobby as far as replacement parts are concerned.
