You mentioned the Philco manual and going through the check points...just to be sure we're on the same page here's the manual from our library: https://philcoradio.com/library/download...6-1947.pdf
I'm assuming you changed the dual electrolytic caps as well as all the paper ones, probably would not work at all if you had not. Static can be hard to track down, at least for me. No one else has chimed in so I don't think there are many more things to try. One thing I've seen is dirty tuning cap and/or dirty volume control can cause static. Try it in different positions around your house as well. Maybe there is a quieter spot.
If you tap the IF cans z300 and z301 and the static changes a lot or it sounds microphonic then the caps in the IF can may be faulty. I don't know if SMD silver mica disease) is a problem in these sets or not. I have a 1949 set that suffers from it and is causes popping and high and low volume at random times but is very bad when the IF can is tapped on. Just a few thoughts.
