Well, I fixed the damn thing. You were right about those sockets, I did find 2 intermittent ones after all. It was a 6EJ7 3rd IF and the 6BN6 Sound detector. That loose connection on the 6EJ7 was causing the drift, and to think I already checked it once and totally missed it. When I wiggled that tube the picture went haywire. The 6BN6 was causing the whistle and pop in the audio. It is still hard to properly obtain yellow, it likes to be a bit green. If you turn the tint to fix it, it messes up the flesh-tones and red areas. It makes them "pinkish". This is why I think there is some issue with Chroma, I'll flip 'er on it's side sometime this week and check the plate voltages on the 6JU8s and go from there. But other than that the picture is very nice and stable from cold to warm, greyscale looks great, bright white and true black. Checked CRT again to be sure it can be ruled out, excellent and equal emissions. Thanks for your advise Doug.
