Thanks, I might need one of those flybacks. But, I checked the flyback for continuity, and it was fine, despite all the red goop that came out of it. There was also some HV ontop of the 1B3.
I located the major HV problem. With all the monkeying around with this set that was done by a previous owner, I should have thought to check more closely in the HV compartment. That 3.3 ohm resistor going to the 1B3 filament was just removed and bypassed. The 1meg resistor from the other side of the filament carrying the high voltage to the crt was nearly burned out (it read 15meg).
While that shouldn't be too hard to fix, unfortunately there is more: the horiz width coil was damaged, it was just left unconnected on one side, and that .05 mfd capacitor across it is missing. The coil at least is not internally broken, but it appears as if it may have lost a few turns. I think I'm just going to try it as it is. Does anybody know the voltage for that .05 mfd capacitor I'm missing, the schematic I have doesn't tell me.
