Bryan-

I have a set of TV tweaking tools that includes one or two with a flat blade flush with, or slightly recessed inside, a hollow shaft. They work quite well on those adjustable coils and small-size slotted pot shafts. You should be able to find some from GC (if they are still around) or another supplier.

Here is a link to a few pictures of my CTC-5 Super with the same chassis. I still need to find and fix a problem in the color circuits that causes the ghost-like video.

Thanks, Chris, I'll do some searching. I have a pretty good collection of old diddle sticks but not one of those.

Usually color TV sets use a delay line on the luma signal, to compensate for the delay of teh chroma demod circuits. If that delay line doesn't have a proper termination resistance load, it could cause an echo (ghost).

Yes, looks like a delay line problem - check the delay line ground as well as resistor values in the video amp circuits.

Bob,

Outstanding restoration. My very first color set was the same RCA "Aldrich" Special model. I bought it used in 1962 and it produced a great picture. Like that rare optional base as well.

Thank you for the tips. I will check the delay line and associated circuitry when I get back into the set. I will be happy if I can get it looking nearly as good as Bob's picture.

Yowza that picture looks fantastic, congrats on the restoration Bob. I think I'll go to bed now and watch something on my CTC-5 in my bedroom before I go to sleep : )
The contrast/brightness mod is on my to-do list.
