The article highlights the restoration of the 1924 RCA Radiola III, a battery-powered regenerative type receiver. The receiver's two WD-11 tubes are equipped as a regenerative grid leak detector and a stage of audio amplification. The batteries used to power up the receiver took up more room than the radio itself. Series resistors in the detector and amplifier plate leads would be utilized to lower the excess voltage.
