  • Notes
  • There are two versions of model 39: the 39B cathedral (1934-35) and the 39F floor-type console (1935). Both are battery operated 2-band receivers.

    Chassis marked as model 39 have no ballast tube and are designed for use with a 2 volt storage battery for filaments. Those marked 39A have a type 6 ballast tube and are designed for a dry battery (presumably 3 volts?) for the filament supply. Three C batteries are required: two at 3V with separate connections for both + and -, and another at 7.5 V with a common + connection.
