The mica caps in the pushbutton assemblies of those 1939-1942 Philcos are usually bad. Since they are only insulated with wax, they tend to absorb moisture over time.

370 pF is not a standard value any more, you can use 390 pF with no ill effects. Be sure you use new mica caps, or NP0 ceramics. Do not use regular ceramic caps as they will make the alignment of your pushbutton presets drift. Don't ask me how I know this...
