Hi Mike and Welcome!
Well it looks like the chaiss is in good shape. The 6A7 tube shouldn't be too hard to find. Aside from the a fore things you mentioned it looks like you got some rubber wire to deal with. You can replace it or sleeve it with shrink tube so you won't have any shorting problems. Would worry about the power transformer being bad too much as usually when they go they will leak some wax or tar. It looks ok. If it has rubber wire (in power transformer) you should pull it apart and replace the wire inside the bell (case) Definitely replace the filters. The diagram for it can be found here http://www.nostalgiaair.org/PagesByModel...013298.pdf Those would be #70-72. Ought to be a great sounding set with the push/pull #42 tubes and a real phase inverter (not seen on a lot of Philco's ) and last but not least negative feedback from the output stage to the preamp. One of the nicer/more expensive sets for '39

When my pals were reading comic books
I was down in the basement in my dad's
workshop. Perusing his Sam's Photofoacts
Vol 1-50 admiring the old set and trying to
figure out what all those squiggly meant.
Circa 1966
Now I think I've got!
