Reformed the remaining electrolytic capacitors. I have run the electrolytics at full rated voltage for 24 hours and the leakage current is acceptable. Next to the paper capacitors.
I have lifted one end of three coupling capacitors. The leakage is pretty bad: the video amplifier coupling capacitor was 4 Mohms and will need to be replaced. The audio coupling capacitor is 40 Mohm and I think I will change that. Any capacitor with an appreciable DC voltage across and leakage should go. But there are a number of places where the leakage does not matter and I think I shall weigh on retaining a bunch.
As for the resistors, there is generally a pretty great leeway and even if out of tolerance, unless the resistance is critical, I will likely retain all the resistors.
