• Notes

• The Navy 6000-BAC morale receiver was made by Industrial Tool and Die Works of Minneapolis, Minnesota under Navy contract N140 S 70560A. The receiver is designed for 3 way power. It can be operated from 115 volts AC or DC or from an external 6 volt storage battery. Its dual band coverage includes the standard AM broadcast band as well as shortwaves from about 5.8 MHz to 16 MHz. The seven tubes include 4 loctals, a 7B7 as RF amp, another 7B7 as IF amp, 7A8 as converter, 7C6 as detector/ AVC/ and audio preamp, and 6G6 for audio output, all of which use a filament of 6 volts at 150mA. It also has two rectifiers, a 0Z4 and a 35Z5.  A vibrator and transformer feed the 0Z4 as in a typical car radio of the era. The 35Z5 supplies "B plus" voltage when 115 volt power is selected.  When operated from 115 volts, one side of the power line is connected to the chassis.

  N140 has been identified as the Naval Supply Research and Development Facility in Brooklyn, New York and the contract has been dated to May 1945.  Most of these radios were intended for the Marines and the war in the Pacific theater, but most were likely used during the occupation of Germany and Japan as troop morale receivers.
