Hi, welcome to the Phorum!

This is a common problem with the Philco radios that use the autodyne converter. The most likely cause is the oscillator coil has drawn moisture. The fix, remove the coil and bake it at 250 degrees for about 20 minutes. Afterward, it would be a good idea to seal the coil with lacquer or clear acrylic enamel spray. I agree, don't mess with the alignment.
