I went and tested the HO tube, h osc tube, damper, and HV rect, HO tube tested a bit weak on the emission test but showed a lot of heater cathode leakage, horiz osc only slightly weak, damper tested ok but also showed alot of heater to cathode leakage, and 1B3 was weak. So I just went and swaped all of them at once to see what would happen, the picture tube lights up strong now, HV is good. I didn't have a 12AU7 (horiz osc), so I swaped it with a modern equivalent, a ECC82, I hope it will sync. I didn't have an antenna hooked up before, so I couldn't tell, now I'm going to go back and try. Power trans is still buzzing, I sure hope it doesn't short out, this set uses an unusual 2 tube power supply (5U4 and 6X5), so a replacement won't be easy to find.
