I also fed capacitor coupled composite video into grid 1 of the 1st video amp (after removing the 4th IF tube), at the time and got a very good picture.
I'll try both of those things tonight. Previously, I sent in an IF signal through the first and then second IF stages and got a picture with the same symptoms. I haven't tried composite directly into the video amp yet.
