I did fool with the AGC seems to be working (goes from washed out to over contrast, but never breaks sync, but then again the box may not be putting out a strong enough signal to make that happen).
Good new!! after yet another tube swap on the 6GF7, I get a good clean sweep. I can adj the vert hold for an easy to obtain non paired up screen. It pays to have a LOT of NOS tubes. While I have a good Mu tube tester I dont know how sensitive the grid emisson test is (its a mercury 1000). I am calling this one fixed, at least that part. One last little issue, seems like I often have to change the channel back and forth when the set is 1st turned on or even if I just switch signal source. The screen will black out, sound is still there a bit weaker but there. one flip back and forth and all is good.
