What percentage? I feel I am almost to the point where the real restoration may begin. Re instituting the removed chassis section will take another full day to do it properly. And then replacing all the paper capacitors and tidying up previous repairs. The power supply needs work: what to do with the ballast resistor And all the filter electrolytics. RCA used excellent quality electrolytics in the late 40's and early 50's so I will be curious how the CT-100 filters will be. And there is refinishing the cabinet while the weather is good.

I would like to think I have nearly reached the 50% point before the first power.

I have learned a lot about the curious nature of the CTC2 chassis design. It does not feel like a big run chassis from a number of little anomalies I have found such as component placement. Certainly with the high number of power resistors, at 475w it is not a power efficient design.
