PW knob has worm gear drive box. Large dial with changing numbers gives a logging scale from 0-500 equivalent to a scale length of 12 feet, In addition, a slide-rule direct-reading scale is ganged with the PW dial to show frequency setting directly. The scale drum can be rotated to change scales. Plug-in coils for separate ranges.
A push-pull audio output stage delivers 8 watts at less than 10% distortion. Output impedance is 8 and 500 ohms. A high impedance phono-jack is located on the chassis, and a phone jack is provided on the receiver panel.
