Have you verified your horizontal hold control has a good solid carbon track? For how fast that jumps in and out, it seems as if there's a intermittent connection. Or possibly a mica cap intermittently breaking down, or even a socket or cold solder joint? And in what condition is the dag on that CRT, that is if it's relied on as the only filter for high voltage. I think it's ability to self restore is a clue that's an intermittent contact point.
