Hi everyone,
I have a Philco 52-944 that I recently re-capped and can’t get a signal out of it. Hopefully someone can give me a tip as to what I’m missing. I may hear a faint crackle or hum in the speaker but no radio signal coming thru. I have checked everything that I could think of, tubes, transformers, tuner, I retraced the schematic, checked continuity throughout the band selector. I even have a 53-958 that I compared wiring. Now here’s the big clue, I replaced the selenium rectifier with a diode and adjusted the following resistor to get the 130v (not what I expected, 15ohm gave me 132v), the 120v called for at the 70mf electrolytic was 116v, but then the voltage at the 3rd electrolytic was only about 40v and the preceding 470 ohm resistor gets blistering hot.
Can you help lead me in some direction?
Thanks,
Alan
