Every year, Popular Mechanics featured plans for a receiver dubbed the “Little Giant,” and these gentlemen are putting together the version described in the magazine’s March 1945 issue.
Despite a war going on, this set was somewhat more elaborate than most. It featured push-pull audio, with two 6G6-G tubes driving the speaker. To drop the voltage for the filament string, a 40 watt light bulb was used. It could be mounted on the chassis, or a lamp could be plugged in to the radio. The set used a TRF circuit, and the magazine recommended a 75 foot antenna to pull in distant stations.
