This WW2 Popular Mechanics project was designed for use during city black outs where power was off.

The radio uses only a 6 volt battery to operate the regenerative detector and a single audio stage. The

receiver works quite well with only 6 volts on the filaments and plate circuits.

I built the receiver using type 6K6 tubes. These tubes are normally used for audio output on vintage receivers.

They lend themselves useful for low plate voltage operations.

By wiring the filaments in series and operating the receiver on 12 volts the set operates on more than double volume.

The hardest part to find for this radio was the vintage cigar box donated for the project by K6VIP.
