  • Notes

  • The Fairbanks Morse 6C is an battery operated, 6 tube BC, Police and SW band chassis used in various models. Has 5.5" dial with a 16:1 tuning ratio.  Also has tuning eye, copper chassis, AVC, tone control and 2 stage audio circuit. Has BIAS CELL in grid circuit of 6T7G detector/triode tube. Uses vibrator circuit to create the B+ voltage.

    Band Frequency Ranges are as follows:
    BC Band......................540 - 1730kHz
    Police Band.................1.7 - 5.7MHz
    SW Band....................5.6 - 18.3MHz

    NOTE: 6C is the chassis number and NOT the model number.  Please post pictures of the radio's on the appropriate radio model page and NOT to this page.

    The following models use the 6C chassis and schematic:

    PRODUCTION CHANGE NOTE:  A production change was made on the chassis, changing the 2W, 10 Kohm resistor (Reference designation 15 on schematic) to a 2W, 22Kohm resistor, which is in the screen grid circuit of the 6D8G and 15 tubes (See Riders volume 10, changes section 10-2).
