It is possible to add DC restoration and there are articles on it in period TV repair magazines.
There probably is a retrace line suppression circuit in that (if not adding one ain't hard) should be from the vertical output to the video...play with the RC time constraints and see if you can improve things.

I understood about half of that. What are RC time constraints? What does DC restoration do, exactly? Is that only for hiding the retrace? Because I could care less about the retrace. The contrast is not stable, that's the real problem.
