The plans for this handsome little one-tube receiver appeared 75 years ago this month in the April 1947 issue of Radio News.

The magazine noted that this simple circuit was one of the most useful pieces of equipment you can build. Obviously, it could be used as an extra receiver, but could also be put to other uses as well.

One half of the 1G6-GT tube served as regenerative detector, with the other half serving as audio amplifier to drive a pair of magnetic headphones. (The article points out that crystal earphones wouldn’t work with this circuit.) It is mounted on a 5 by 7 inch plywood base, with a front panel made of sheet steel. With four plug-in coils, the set would tune from below the broadcast band up to 18 MHz.
