I discovered the HV stuff comes out easily on it's own subchassis. Much easier to work on. The flyback looks like the same FLY-1 type used by Admiral, RCA, etc.



It tests good but the wax coating is in crummy condition. S I took it apart and recoated. I've done it before and it's fairly easier to take apart and reassemble.


I used some microcrystalline wax that is harder and has a high melting tempo than beeswax.


Found a charred 4.7K power resistor that measure about 2 K. I'm using little reddish 2W Vishay metal film resistors. I think they are less jarring than the bright blue types.
