Add RCA Component Sound And Video Hook Ups

I think you'll see the biggest jump in image quality if you can modify the set to accept "S video". That's separate luma and chroma, not mixed together. This would be non-trivial to do, though, you need to find the chroma luma separator (usually some sort of LC trap or bandpass circuit). Then you have to inject (with the right amplitude and polarity) the luma into the circuit that received the luma from the separator, and chroma the chroma.

As for hot chassis sets, an isolation transformer would be best, but be careful where you install it, to keep stray magnetic fields out of the CRT.

That will work to create composite video that will have minimal cross luma into chroma errors in a notch filter color TV set. If the TV set in question is a notch filter set, the luma bandwidth that you see on the CRT screen is low pass filtered to avoid the appearance of the chroma subcarrier (a crawling fine grain checkerboard pattern atop highly colored areas of the image).

True S video would produce about twice the resolution than the above composite video maker. But this composite video lets you not need to dig deeply inside the set's color circuits.
