1945 “Little Giant” TRF Broadcast Set

1945MarPM31945MarPM1Every 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.
