Did some more poking around today. Seems the dot issue goes away when the brightness is left up before poweroff; then when the sweep decays, most of the remaining emission has already gone and a fuzzy spot is all that's left.
Still having issues with foldover on the left hand side though. I tried subbing out the cap on the cathode of the damper tube (schematic gives option for .1 or .03) but no change. Same with the .47 vs .22 on the cathode of the damper tube.
Apart from desoldering and checking every single resistor in the horizontal section, does anyone have any tips as to specific things to test? I also note there's a resistor buried somewhere inside the horizontal yoke... Hope that's not the problem.
