Looking at the schematic for the 39-45, I noticed it has a real, tuned RF amplifier stage, and a three section tuning condenser. So your radio should be an excellent performer when you get it going.

Unless you want to restuff those old wax capacitors, metalized film (yellow) caps work very well as replacements. It's what I use...and I usually buy mine from Bob's Antique Radios in the Chicago area.

Two vendors are offering 1939 Philco pushbuttons.

The originals were translucent, red (wine) in color. Be sure you ask for 1939 Philco pushbuttons. They are made differently than 1940 and 1941 Philco pushbuttons.
