Philco used a number of .006 paper-wax-foil capacitors in these radios. They are in the audio circuitry used as coupling capacitors. I decided to replace these with .01@630V capacitors instead of ordering .0062 capacitors. I reached a stopping point late today and will do more tomorrow. I noticed that the terminal strips have solder lugs that are made for simple wrapping rather than feeding leads through a hole in the lug and then wrapping. This actually makes replacing parts easier. It likely made assembly at the factory easier also.
The schematic that seems closest to this radio is a Beitman's schematic. Their schematic shows the deleted B+ Choke and a simple resistor substituted for the choke. The value may vary depending on the production run. This one looks to be about 1.2K ohms and around a 6 watt resistor (which could be less than 6W).
