25v vs Roundie

Maybe try a close comparison of the CTC-17 versus CTC-16 (or CTC-20) schematics. There might be some good clues there.

I did just that, not much, mostly the adding of a picushion transformer, but maybe a change in the fly as well. I think part of the problem would be the top and bottom pincushion, as there is no coverage of the mask there, and I assume with the sharper deflection angles you really need pincushion correction all the way around. I am just going to back burner it for now, If the occasion arises I way at least see how the CRT would fit.

The CTC20 chassis was in a class of it's own.
RCA engineers took a newer design, entry level model, CTC19/24 and made a roundie model, to use up cabinets, bezels and CRT's.
The flyback was special to that chassis and was an order item.



I worked on a 20 that had a real hi-end cabinet, intended for a CTC16X.
