  • The Fairbanks Morse 4BC1B is an battery operated, 4 tube BC band receiver.  Uses chassis 4B. BC band frequency range is 540 to 1730kHz.  Has bias cell used to bias 1F7G tube.  Also has AVC and 2 stage audio circuit.

    The 4A and 4B chassis are the same chassis, however the 4A chassis came with a battery cable used to interface with standard A, B and C batteries, while the 4B chassis came with a synchronous vibrator power supply and cable used to interface with a 6V storage battery. Both the battery cables and the vibrator power supply have plugs, making them interchangable to the chassis.

    NOTE: 4B is the chassis number and NOT the model number.

    The following models use the 4A and 5A chassis and schematic:
