The ceramic disk capacitors, like molded micas, can go bad sometimes too, but it's rare, although the earlier production disk caps were more prone to failure then later ones. In a Philco from this era I would pay close attention to the carbon comp resistors, they did not exactly use ones of the best quality, and they are starting to cause problems now.
