1942 Crystal-Tube Set


Shown here from the September 1942 issue of Popular Mechanics is a crystal/tube receiver built with junkbox parts. The construction article noted that the set “really goes to town” by combining the fixed crystal with one stage of audio amplification. This set was built into the case of a broken clock, but the article noted that another suitable enclosure could be used. The author noted that many distant stations were pulled in, especially at night.

The batteries were mounted inside the clock case on a base made of cigar-box wood.
