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.
Although I grew up in the '50s helping my grandfather in his radio/TV repair shop, my memory of these details is fuzzy. However, can say that the electromagnetic coil isn't powered by 6v DC as AC or pulsating DC is needed for an electromagnetic coil to work. It should not be too difficult, though, to see in the schematic whether it can simply be disconnected or whether it is part of the voice coil assembly's functionality.
