1933 Four Tube Superhet

1933MarSWCraft85 years ago this month, we see this young radio enthusiast who just managed to wake up his parents at 5:30 in the morning. When they came to investigate, they were shocked to learn that he was pulling in Australia with the four-tube superheterodyne described in the March 1933 issue of Short Wave Craft magazine.

The set employed two tubes in the RF section with an additional tube serving as AF amplifier. The set ran off AC power, and contained a power transformer and rectifier completing the tube lineup.
