I looked up the schematic for the CTC12. I was trying to see if that chassis used a focus rect tube instead of the stick. I remembered that it uses 6FQ7's instead of 6GU7's. Also a 6DQ5!

IIRC used a tube. Sockets would burn.

I replaced one or two of those carbonized messes. It nice when there are obvious clues to where the problem is. Initially, this set had an arcing and lit-up vert centering control.

I like the fact a 12 is similar to a CTC11, (my fav) but rearranged and with some improvements.
The combined luminance/chroma PW700, I do not consider an improvement.
