The March issue of Popular Mechanics typically carried the plans for a receiver dubbed the “Little Giant,” and despite the war, the March 1943 issue was no exception.  The couple shown above are putting the finishing touches on the set.

Wartime parts shortages were taken into consideration, and the set could be constructed with many parts found in the junk box. For example, the coils were wound on the cardboard forms retrieved from an old flashlight battery.

The circuit was a simple 3-tube TRF set, using a 12K7GT as RF amplifier, 12J7GT detector, and a 70L7GT AF amplifier driving a PM speaker. With a good antenna, the set would pull in stations a thousand miles away, but still had good selectivity for use even in a city with many stations.
