Welcome to the Phorum. Some of the more experienced folks will have experience with this specific model but if it has never been recapped you do need to do that to avoid damaging the transformer or other parts of the radio. The electrolytic caps and paper caps (which in this radio are probably inside of bakelite blocks....see: http://www.philcoradio.com/tech/blocks.htm ) need replacing. A schematic can be found here: http://www.philcoradio.com/tech/images/15.jpg : additional info beyond the schematic here: http://www.philcorepairbench.com/schematics.htm . Some useful info if you've never worked on a radio is here: http://www.antiqueradio.org/begin.htm .

Try the folks on this list for the knob: http://www.philcoradio.com/resourceb.htm#l

Lots of threads on this Phorum about refinishing the radio correctly as well, just do a little searching around and asking questions.
