Hey jcassity - thanks for all your help! I haven't been ignoring you...just getting around to replying. I'll try to cover all your points.
"...your utilty line voltage is higher than in 1947....lets assume you have 124vac." I'm driving the radio with my variac set at 117v
"I see two sets of FM instructions from post 141 and 150." Sorry about the confusion. The Philco documentation has a set of AM tests. If it passes those you move on to the FM tests that I referenced in post 150. If either set of tests fail you move on to more troubleshooting tests. The subsequent FM tests are referenced in post 141.
"i am going to backpedal your posts to see if i see your FM being able to use an alternate means of signal reception other than an aerial FM." I don't think my radio uses the power cord as an antenna.
"set a small modern radio next to your set and tune to a station that comes in on FM." I tried this but didn't hear any kind of difference in the modern radio when I tuned through the FM band. I think this is just more evidence that the local oscillator is not running.
"it looks like you have a pair of wires factory installed from the 4 position terminal block." I'm not following what you're referencing here. What 4 position terminal block? EDIT: Just after I typed this it dawned on me that you must be talking about the connector for the FM antenna, right? If so, yes, I do have continuity from pin 4 to ground. I'll have to jumper across C410 and do that test later.
Thanks for your help...I appreciate it! I'm still hunting.
