As Nick mentioned earlier, he has sent me has hand drawn schematics and I'm cleaning them up and digitizing them. I am almost finished with the IF/sound sections, and have found what may be some evidence that the set is from RCA. There are 4 video IF stages, and they are very similar to the design in the CT-100, other than the fact that there are 5 stages in the CT-100. It is possible that RCA IF transformers were used by another manufacturer, too. I will be posting this part of the schematic soon.
