I started cleaning the exterior - 30+ years in a attic down here isn't kind. There's some light corrosion on the mask and slight discoloration on the bezel behind the dial. Still, it's cleaning up fairly well.
I opened the HV cage to examine the flyback since I saw the wax was flaking off. While gently working the HV rectifier tube the whole socket came out of the insulator - looks like it cracked apart where the screws threaded in. There's also a 4-section electolytic can on the chassis that must be a replacement, because it is so tall it all but touched the yoke windings, and the repairman just wrapped electrical tape around the top of the can.
