have you replaced all the filter caps or checked them. there are some on the vert xformer primary that are decouplers as well.

did you check all tubes for HK shorts

Did you reflow all ground stakes, on the PCB's

Generally speaking a slow moving vert wave (vert line has horz displacement) look for hum and vert osc rate beat freqency issues. I had a maggie like that turned out it had a poor ground connection on the sweep board that allowing heater ac interact with the sweep. The prevailing opinion was a beat freq of the 60hrz vs the 59.999 whatever of the vert osc somehow modulating the horz (the horz displacement). Anyway check out the above.
