I removed the CTC-2 chassis and checked it over. It appears that rather than a restoration, it was repaired in the 1980's but most of the original capacitors are still in place. Here is a picture:
Many parts have been replaced, but there are lots of old electrolytics and paper caps in there.
For you CT-100 experts out there, are these some of the peaking coils that go bad? One that is not visible in this picture has green corrosion on one of its leads. The picture above shows one white and three brown coils; I think I have read that maybe the brown ones will be OK? In any case, is there a good source for the needed coils?
The transformer wrapped in black tape is jammed between the other transformer and the back end of the tuner housing. I found out this is an added-on filament transformer. My tests of the CRT (in the original topic for this set) showed it has a heater-to-cathode short, so this part has to stay, but I hope I can find a better/more-secure way to mount it.
Overall, this is going to be a bigger project than I expected at first, but I have no hesitation about getting the job done. However, I have not previously done a full/major restoration of a chassis before, so I am going to pick another set of mine to do a "complete" job on first before taking on this top-of-the-chart one. That way, I will have a good amount of hands-on experience before jumping into the CTC-2. Likely, it will be an RCA 8TS-30 I bought a year or so ago. I will post updates here as I move forward.
