content: Marked: "Signal Corps, U.S. Army / Airplane Radio Receiving Set / Type SCR 59 / Serial No. [blank] / Order No. W4076 / Made by Western Electric Co., Inc." Plate on top of unit reads: "Patented in U.S.A. / Dec. 2, 1902 / re. Aug. 4, 1903 / re. Aug. 25, 1903 / Aug. 16, 1904 / April 17, 1906 (2 patents) / Feb. 18, 1908 / June 6, 1911 / July 14, 1914 / March 2, 1915 / Patents applied for." The SCR-59 receiver is almost identical to the receiving section of the SCR-68 Transceiver. It is designed to be used in conjunction with the SCR-68 set. The circuit is a VT-1 detector followed by two VT-1 amplifier tubes all supplied by a 4 volt, 22.5 amp-hr. storage battery, type BB-4. Plate voltage is supplied by two BA-2 batteries mounted in the same box. The set is tuned by inductance coil taps and a variable condenser. Two dial controls vary inductance and capacitance in the circuit. Two pull-type switches mounted on the panel. One cuts a resistance in and out which shunts the second amplifier; the other pull switch cuts the filament current supply on or off.
