  • Remarques
  • The Philco model 37-643 series (1936-37) uses a 7-tube 3-band battery-powered chassis with shadow meter (tuning aid). The chassis is similar to that of its predecessor, the model 643 series (1935-36), but updated with newer octal tubes. Filament power is provided by either a 2-volt storage battery, or by a dry battery (presumably 3 volts) with a 1Z1 ballast tube inserted into a socket on the battery pack.

    There are three specific models in the series with different cabinet styles. Model 37-643B is a tombstone. The early version (1936) of model 37-643X is a console with inclined sounding board and six very short legs. The late version of 37-643X (1937) has a large U-shaped inclined panel including both the speaker and the control panel, and no legs.
