OF course they can be made to work again, as long as we can get
guns. At worst, due to the way the front end is made, the metal parts
could be installed in a completely new glass envelope. The problem
is getting alignment good enough for ok convergence.

The price I'll pay .... I'll give no number, but note that I own a TT5 and a Marconi 702.

I'm still considering replacing it, at least temporarily, by a rectangular Trinitron tube
that does not need convergence, and a fake external mask. I will try talking to people
about that at the ETF. If I ever succeed, it would make a great ETF talk. The problem of course
is horizontal drive ... maybe use the transistorized board of the donor set?
My comment about watching the set while the tube is good didn't apply to you Doug. You seemed to be playing your CT-100 very often, at least from what you posted on VK. That's the way it ought to be. Use it before you loose it...

I was referring to a collector that I know, who shall go nameless, who watches his restored CT-100 once, or at most twice a year, in order to "save the cathode material". You can have the best cathodes in the world, but if the tube is gassy, it doesn't matter.
