Seventy years ago this month, the July 1954 issue of the British publication Radio Constructor carried the plans for this one-tube regenerative receiver for the “veriest beginner” to radio. The magazine noted that such a beginner may not yet know how to read schematics, and the the magazine thus carried Heathkit-style step-by-step instructions for wiring it up.

Future issues of the magazine would add improvements, which would ultimately result in a three-tube set.
