Fidelity of Tone Musically cultured people prefer Stromberg- Carlson Receivers. Those who appreciate fine violins, grand pianos, hoxes at the opera and season tickets to concert courses know what well-played instruments sound like. They wish to appraise the playing of Hofl- man, the singing of Homer, the technique of Seidel as accurately by radio as though seated before them. They prefer a Stromberg-Carlson Receiver be- cause of its faithful tone reproduction. This fidelity of tone is due in large measure to “Rejectivity,” an exclusive Stromberg-Carlson feature, made possible by totally shielding each radio frequency circuit. Any authorized dealer will gladly demonstrate the difference between tone which merely approx- imates broadcasting and tone which duplicates it —Stromberg-Carlson tone.

Your radio must have just as reliable a parentage as your automobile. So, start your radio shopping by looking into the name back of the set and its accessories. Any set made today may function eatisfactorily in the hands of expert radio salesmen. but you want a Radio that will “stand up™ and function for YOU—for weeks. months and years. And—like the automobile—when you really need service—you must have it near you—always—reliable—and up-to-the-minute. Right here there's a tremendous advantage in having ALL the Units of your Radio by THE ONE reliable maker. If your instrument is by one maker, tubes h, another, repmducer by still another, and accessories by some “outside concern.” you can hardly expect 100% satisfaction. The entire Stewart-Warner Radio Line is the product of Stewart- Warner. It includes EVERYTHING you need from ground to aerial—the ONLY Matched-Unit Radio obtainable. When you buy it you have only one maker to look te should you ever need service. It srems needless for us to tell you of phe great success and financial atrength of Stewart-Warner. for this has been known fo millione of people for many yeare.
