  • Notes
  • This portable AM-only radio receiver employs 8 SFT-transistors. Fundamentally this receiver is like an average six-transistor set but, in this case, with an extra transistor as audio amplifier before the audio driver transistor. An additional transistor is used like a diode in the class B push-pull stage.

    The transistors used are all PNP types and by SFT. SFT-transistors were built in Italy, in Sermoneta (LT) from the late Fifties onwards, by MISTRAL (Manifattura Intereropea Semiconduttori TRAnsistori Latina) S.p.A. The firms involved in this new company were the Italian MIAL and MICROFARAD and the French Compagnie Generale de TSF. Lots of Italian radio circuits of the sixties were equipped with made in Italy SFT-Transistors.

    This set is powered by four size D batteries (tipo torcia in Italian) connected in series to supply 6 volts. It is equipped with a high gain ferrite core antenna coil and receives AM MW-band from 520 to 1.620 KHz; its output is obtained through a 15 cm maximum lenght elliptical loudspeaker. Even though it was built in 1963-64, this set was assembled using still the for-tube-radio conventional "chassis" type construction rather than the etched circuit board. The two available versions of Binghy differ only in the exterior view as shown in the pictures (courtesy of Wolfgang Gebert).
