So has the set been serviced?? Does it play? If it does play if you flip the switch the the of way does the sound disappear? If so sounds like it's an external input to the audio amplifier. Might be handy if you could snap a pic of the underside. Philco never use phono input on their prewar sets. They believed that it was better to sell you a record play with a small transmitter in to send a radio signal for your set to pick up hence the RP-1,2,3,4. Look Ma no wires!!!!!!
