The capacitor with coil (C401) is a wave trap roughly tuned to 455kHz to prevent nearby interference from other rf sources. Don't know when Philco stopped putting them in but you don't see them in later sets. My experience is there's always 8 turns of wire in series with the cap. You have 3 options; leave the coil out of the circuit, wind wire on a new cap, or remove it altogether. I think most use option 1 and put in the cap only. This is one of those things where you want to be a fly in the room during the design discussion. (Hamilton: "I want to be in the room when it happens!" )
