Default Bush TV22 flyback pulse

I seem to be stuggling to get good EHT from my TV22. When the brightness is turned up the picture expands and defocuses ending up with a blank screen until the brightness setting is reduced again. I am wondering if this could be caused by incorrect flyback resonance. The flyback pulse at the LO anode is in excess of 800V but has a kink in it (see attached). Any advice appreciated.
