  • The General Motors model 120 "The Hepplewhite" 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:  A style named after its creator, George Hepplewhite, a cabinet maker of England whose design began to influence British furniture-making about 1760.  Noted for the use of straight lines and graceful curves.  This model is a simple, graceful lowboy in harmony with practically any setting. 

    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:
