  • Notes
  • The General Electric C-105 is an AC/DC operated 5 tube BC band receiver.  The BC band frequency tuning range is 540 - 1600kHz. Has built-in loop antenna with provisions for connecting an external antenna. The models with these serial numbers have a record player input jack.

    The following models use the same schematic and chassis but have different cabinets:

    Model Cabinet
    C-100 Brown Plastic
    C-101 Ivory Plastic
    C-103 Mahogany Wood
    C-105 Maple Wood

    Note: The following changes were made on models having serial numbers of R107180 to R108179 (Per GE Service Manual):

    a)   Eliminated R1 470 Ohm resistor in antenna circuit and uses tapped loop antenna.
    b)   R2 10Megohm resistor eliminated.
    c)   C6 eliminated from oscillator circuit and a new oscillator coil is used.
    d)   A phono input jack has been added and a shorting bar added to the rotor of the oscillator section of the tuning capacitor that shorts the oscillator when the record player is used.
