So far, it's been recapped and I've replaced all the out of tolerance resistors I can find. It produces a reasonably good B&W picture, but the chroma is VERY noisy. It looks like the kind of noise you see if the fine tuning is way off, or with heavy RF interference, but the picture looks good with the color turned down. Sound is also good.

I'm not sure what's normal for a CTC4, but I find that I have to set the color control a lot higher than on most other sets. I suspect it could be a problem with the chroma band pass (misalignment or low gain).

I have not checked the alignment yet other than the basic chroma demodulator adjustments. I can do a full alignment if I have to, but this one looks like a very complicated job.

Your set sounds like a carbon copy of mine. Same problems. It's probably a matter of IF alignment.
