Amen! That's a solid fact. Chris, you've received a number of suggestions so far. Let me add mine: I see only one white inductor on your chassis; it's a little distance from between the red and blue boards (they contain the circuitry for the matrix and R, B, and G amps). Check the continuity of that white inductor. If it's open replace it; if not, leave it. Replace it when it opens, if it opens.
My reason: I personally would rather have the original RCA part in the chassis with its factory-defined specifications. I can see the 6.7-uH coil in the Q filter was replaced sometime in the past in your chassis. On my site I had a page describing how the function of that stage deteriorated when the factory part was replaced with the
NOS 1954-RCA-specified replacement part listed in SAMS.
Also, in my estimation, those three video boards have been restored; I would not repopulate them unless you found out-of-spec components.
Enjoy your CT-100.
Pete
