This handsome 3-tube shortwave receiver was put together during the war by Harry D. Hooton, W8KPX, as reported in the September 1945 issue of Radio News. He reported that at the outbreak of war, he sold his receiver and other equipment to the U.S. Army Signal Corps. But before long, he had the urge to build something, and this set was the result. He was able to find many of the parts in his own junk box, and acquired others by very carefully negotiated trades with other local hams.
The set covered 2-20 MHz with three plug-in coils. It used three tubes, plus one rectifier in the separate power supply. Hooton reported that he constructed the power supply separately to avoid hum in the high-gain audio stage, and also to make the set usable with batteries if desired at a later time.
The set used a 6SJ7 as RF amplifier, followed by a 6SN7, a dual tube used for regenerative detector and audio amplifier. This went to a 6C5, which was a second stage of audio amplification.
