Oh, one other item I noticed. I dug through my tube collection and found a good 6KE8 to replace the improper 6GH8A that was erroneously placed on the chroma board (there should only be one on this chassis for the chroma osc). Some things settled down a bit and with a strong signal, was able to attain a very clear picture...except for a couple of things.

There is a faint, vertical, red bar on the right 1/3 of the screen about a quarter of an inch wide running from top to bottom. Additionally, there is a single ghost just offset to the right of the image. Now I have noticed that none of the IF tube have their shields on. I am sure this is having some affect on the signal processing and a dirty tuner I am sure is not helping. The vertical red line is puzzling to me though.

But that could well be solder connections and/or low b+ voltages. Any thoughts are appreciated.

screen voltage

on the older RCA sets, always check the resistors in the screen circuit for change in value or burnt resistors.
