Philco 42 380 Hums well but does not know the words

My guess would be that the power supply electrolytics are gone. The very first thing to do with any old radio is to replace these capacitors to prevent damage to the radio's power transformer and to get the hum issue out of the way. When the caps are bad you are putting pulsating DC out on the power supply lines, thus the hum.
