John,
Looking good. The crt makes a good white in the first picture and the convergence from what you can tell from a thumbnail looks good too.
My CTC10/11 has only a B&W picture and I have not pulled the chassis to diagnose it further than test/replace the tubes in the chroma section that made no difference. It doen't even appear that the burst gate is opening and rocking the H. hold didn't affect it at all.
Playing with my vintage TV's has taken a back burner status with my recent push in audio R&D.
Are you planning to sell this one too?
Rob
