An unnamed soldier at Camp Gordon Johnston, Florida, sent in this receiver circuit to Radio Craft magazine, which published it in the June, 1945, issue.  The soldier reported that he constructed it in his barracks, using various parts gathered around camp. He reported that it pulled in all local stations loud and clear with loudspeaker volume, using a 45 volt battery.

One half of the 1D6GT tube was used for the detector, with the other half serving as audio amplifier.
