I decided to rewind the video IF transformer. You can see the progress below. It would have been easier if my eyes weren't the same age as the TV.
After installing it, it has a strong video signal.
I have have a horizontal problem. I'll go through the horizontal alignment procedure and if that doesn't fix it I'll have to do some debugging.
I'll need to realign the video IF also. But, I need to do some work on my Hickok 610A first.
