An update. The intermittent local oscillator refuses to quit, as usual, now that it’s on the workbench. I got it running by the usual ”shock excitation” method by touching the grid of the 36 osc/mixer with a short test lead. And now, it won’t quit. Plays for hours. When it finally does die, again, I’ll check voltages. But running properly, it has 90 Volts on the screen and about 260 on the plate...that should be more than enough to keep it oscillating.
