It would be interesting to hear what everyone who has a working CT-100 is seeing for focus stability, brightness, and contrast. Mine is almost acceptable now that I've backed off the contrast, and set the HV regulation to around 18 kV.
What it cannot handle well at all right now is a white screen. Quite a few commercials these days include a white screen with some text and a small picture. When a scene like that comes along, I get total focus collapse, with the screen practically going blank in a cloud of fog. Almost all other "normal" scenes are OK.
I'll probably leave it like this for a while and take some time to work on the color circuitry, and come back to the flyback / HV issues later.
