Boy, That's a weird one. At first, it looked like it might be a bad/intermitent connection at the 35 ohm section of R43, which would unload the power supply with no voltage drop across the field coil or op transformer primary. Still can't get to 600v. Tried to make some kind of voltage doubler out of C45 and C15a, couldn't make that work either. Be interesting what the experts say. Are voltages approximately correct when the set is working?
