While waiting on parts I decided to remove the CRT and do some basic above chassis clean up. Apparently this set was kept in a location that allowed condensation to form and drip off the CRT. It's the only place there is significant rust on the chassis.
I also found the break in my flybacks high voltage winding. It was hiding under a piece of insulation tubing going between the windings and the coil tap terminal. Unfortunately I found it after I'd already unwound a couple dozen turns off the HV donut.
I was able to re-flow the wax around the HV donut, and everything is ohming out reasonably close. Only time will tell if I messed up my HV by removing those windings. Not sure if I can get away with running the HV winding wire directly to the solder cup. I suppose it could arc to something and vaporize that tiny wire.
