Philco made the RP-1 and 2 wireless record players to be used on any radio. Their own sets that year, probably did suggest that you could dedicate a push button (PB) to the phonograph. It made the RP players more convenient that way. The screw mentioned above was to set the PB frequency for the player.
Note that Philco either did build a prewar TV receiver, or planned one and never put it into market. In those years, TV sets had no audio amplifier built into them, and depended on the owner using his radio for the TV sound. Philco's TV sets had an oscillator in them, modulated by the TV audio. The radio was set up to tune a PB to receive the TV sound, just as from the wireless record player.
RCA's sets had an audio cable, and connected into a radio's phono jack.
