If there was a dead short in the voltage doubler, would there be enough B+ for the sound section and tuner to work? It did turn on, mind you with a buzzing sound at first (the horizontal oscillator and output tubes were removed), and just kept on vibrating. The tuner and sound section did work, as I got clear sound from the speaker when I tuned to channel 3. None of the electrolytic capacitors got warm or hot. I only changed the 160uF electrolytic that connected to the rectifier and the B+ line that leads off to the filter inductor. It's definately the right polarity, as I made sure the polarity was right because I never never knew it was a voltage doubler until you told me.
I replaced it with a fresh Mallory 160uF 350V from mouser. I checked the ceramic filter capacitors and no shorts, and I made sure the polarity of the rectifiers (I replaced those with fresh 1N4007s from mouser because they were rusted) And checked the B+ winding. Maybe I should check the 160uF capacitor in the multican and see if it has good ESR? It's not connected to the pucture tube, yolk, or convergence board. The seller did test it, and he did get sound, but he got an out of focus and dim picture, so maybe I should change that 160uF capacitor? Any other suggestions?
Thanks so much.
