According to this sitehttps://sites.google.com/site/identifyingcarradios/home the PA-5154 is a Philco 1432 but there might be a P suffix designation on the number. I have a P-1432H schematic but do not know if there is a significant difference between the P or H or a no suffix designation. Not sure it is the correct schematic for your radio but here is the one I have.
The X on several of the wires in various places denotes the wires are connected thru a plug to another part of the system such as the control head or the 3 wires connecting the speaker. Someone else more into radio circuitry will need to say if the electromagnet field coil is actually needed as part of a power supply filter or if it is just being powered off the main incoming 6v supply line and can be eliminated with no adverse effects.
