while futzing with it I noticed the green was a bit weak, after screwing with drive controls, I finally decided to check tubes. Normally if they test a bit low on my mercury tube tester I don't sweat it, and one of them was a bit low. swapped in and color looks a lot better. per my tester SHB 3000, was about 1500, new tube was 2000 for what ever that is worth.
another odd thing was when I tried to use my vector scope the pattern was a mess on color bars. found out that if i disconnected the grid leads (so the vectorscope was not ready the chroma) the color bars on the screen look good, with in connected it was a disaster. I have never had a problem with the vector scope loading down the signal like that before.
oh the tubes where the 12BH7 difference amp tubes.
