From a 1939 Zenith brochure.
|In 1939, Zenith was both following the pushbutton trend ("Push a button—there's your station!") for automatic station selection, and leading the way in complex tone control systems. On the more expensive sets, Zenith introduced its so-called "Radiorgan." An array of six buttons (labeled voice, normal, treble, lo-bass, bass, and alto) that could be pulled out or pushed in (like the stops on a pipe organ) allowed the user to choose one of "64 tonal combinations." These Radiorgan buttons, together with On and Off buttons, are in the escutcheon wing to the right of the round big black dial. The eight "Transcontinental Automatic Tip-Touch Tuning" station selection pushbuttons are to the left of the dial.|
