I changed the 1B3 out of another set that works and replaced the one in the Predicta but no change. I've got all of the B+ voltages...all maybe 10% low due to the age of the rectifier diodes that I didn't change. I'll have to look at the schematic as I can't get to the bottom of the H Osc socket, The choke or the VOT is mounted right under the tube and I don't have a test socket so I can check the bias. The resistor between the HVR and the HV lead to the CRT is right on at 5.5K and the HV lead has continuity. I did find something interesting as one of the wires going into the yoke chassis plug had pulled out of the pin socket but that's probably something I did moving the chassis around. It's been repaired.
