I bought a Philco 42-380X at a flea market. BC band worked fine, SW bands did not function at all.  After exhaustive tube and component testing, I found a factory installed jumper wire on the complex bandswitch which shorted out the oscillator on the SW bands.  After removal of this wire, the SW bands worked perfectly.  I later found out this radio was produced shortly after the Dec 7, 1941 attack at Pearl Harbor and the federal government required all receivers capable of receiving SW to be disabled to prevent spies in the country from receiving information.  Spotting this wire was difficult, as it was exactly the same wire type and coloring as all the other wires on the bandswitch, and all the solder joints were original.  I had to trace each wire.
