  • Notes
  • The General Motors model 130 "The Sheraton" is an AC operated, 8 tube BC band receiver. This radio has four tuned radio frequency circuits using three 224 screen grid tubes, a dectector stage using a 227 tube, a first audio stage using a 227 tube and the final audio stage consisting of two 245 tubes configured as a push-pull amplifier.  The set also uses a 280 full wave rectifier tube.

    1930 General Motors Catalog states:  Named after its designer, George Sheraton, who furnished designs to English cabinet makers between 1790 and 1800.  Noted for charm and delicacy of detail, subtle curves and chaste, straight lines.  The carving is small and finely executed.  This model is a beautifully finished highboy with a serpentine front - something new in radio cabinet design. 

    There are four knobs: Upper left is the tone control, lower left is the power switch, upper right is the station selector and the lower right is the volume control.  The small lower dial is the tone indicator.

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