  • The Silver-Marshall 726SW (new version) is a double conversion super heterodyne receiver, covering 550 to 10 meters in five bands. It has push-pull audio, terminating with the included S-M 855 10.5 inch dynamic speaker.

    As a short wave broadcast receiver, the antenna is fed into the short wave detector circuit using a 24 type tube. A short wave oscillator of special design using a '27 tube, operating at 650 kc away from the short wave detector heterodynes the incoming signal to the frequency to which the RF stage of the broadcast receiver is tuned, the broadcast tuning dial being set on a clear channel at approx. 650 kc for best results. As a short wave super, there are three detectors and two oscillators, giving so called double "suping".
