Thanks for the helpful information so far - I'm looking at resistors now.
The list shows "Flexible Wire-wound" but I don't see anything like the ones pictured on one of the Philco sites. I found the carbon resistors and out of the three I've checked one or two might be too far off to keep. What was the tolerance of the originals (wire wound and carbon)? Additionally, what is the wattage rating for the wire wound? I found the ratings for the carbon, which I am going to just pick up spares for in case I need them.
Is it possible there are carbon resistors in place of the wire wounds? A few more modern carbon comps are installed in the radio, but I haven't verified they are all in place of the wire wounds.
Additionally, is there a good way to check the big voltage divider resistor? Can it be probed in circuit, or will I get false readings?
