never mind, found it, short the sine wave coil, gound pin 2 of the horz osc tube, adj the horz hold for somewhat sync pic, remove coil ground, adj sine wave coil to bring back in sync, jump the coil again to check.

did all that but I still have maybe 1/4 turn at most to flop the osc (using the hold adj), and since it does indeed flop my guess is its a weak sync pulse. I subbed in new sync tubes (sep and amp) but no real change, still very narrow sync range. I am going to have to scope the output from the separator and see whats coming out. My guess is some voltage issue from a drifted resistor. will check the video out as well, maybe something getting clipped before in the IF?
