Ok, thought about your color sync issue. Horizontal is good and stable now? Even if it's drifting a little, color will go out. Make sure your horizontal hold control is set so you move it in either direction an equal amount to determine it's most stable point. (as a side note, is the pot somewhat centered in it's range?). All good here then there's some things to check on the chroma board.

For starters, make sure the 6GH8 for the 3.58 Mhz is ok, as mentioned elsewhere and I agree 6GH8's can test good but still not work too well in the circuit...try a couple and observe your results.

Is yout tint control centered or close to center? (easy fix).

Check the 6EW6 and the 6JU8 tubes too. Grounds and wire leads ok? RCA Chroma Boards have wires running on the component side that will get corroded where they run into the feedthroughs and possibly become poor connections. Solid grounds verify too.

After all this, check voltages on the 6EW6 and 6JU8..ok?
