  • Notes

  • In October 1947, the U.S. military government in Japan ordered increased production of superhets. Until then, Japanese radios had been almost exclusively single- or dual-circuit straight-through receivers (TRF). After the development of a suitable mixer tube and a double diode-triode, the first standard superhets, such as the device described here, came onto the market at the end of 1948.

    Im Oktober 1947 ordnete die U.S. Militärregierung in Japan an, dass verstärkt Superhets hergestellt werden sollten. Bis dahin waren die japanischen Radios fast ausschließlich ein- bzw. zweikreisige Geradeausempfänger. Nach Entwicklung einer geeigneten Mischröhre und einer Doppeldiode-Triode kamen Ende 1948 die ersten Standardsuper auf den Markt, so das hier beschriebene Gerät.
