A RADIO DISCOVERY "Neutrodyne-Plus" A New Term in Radio TERM to describe a novel development due to a remarkable enlargement of the Neutrodyne principle — a discovery by Philco radio engineers. Impartial radio scientists agree that Neutrodyne produces the finest tone quality known to radio. Superbly clear — no howls or squeals — absolutely free from those disturbing oscillations which destroy purity of tone. To this, Philco engineers have added something new — super power, greater than has ever been known to Neutrodyne before. I~hl> i^oci iSS" ^ -^ perfected tone quality plus the acme of distance lllt> l\fSdUIL* and selectivity. Genuine RE-Production. A tone quality never heard before. Close your eyes while listening — and you will hardly realize that you are hearing a radio, the sound waves are so perfectly RE-produced. Piano tones sound like the piano. Individual instruments in an orchestra retain their identity. Drums are not lost — they're there! The human voice comes out as if the speaker or singer were before you. Never before such LIFE-like RE-production. Plus Power Yes, for the first time, full power — super power. Together with that superior tone quality, you get selectivity and range so controlled as not to take away from the tone quality. And this power means Remarkable Distance Getting Stations thousands of miles distant may be heard, in many cases just like local stations. You will get low-power stations you never knew existed. Wonderful Selectivity Yes, marvelously sharp tuning! With a hair's-breadth turn of the control you can often shut out a powerful station completely and bring another — miles away — booming in. Even local stations are confined to narrow limits. In large cities you can get distance, because you can tune out local interference. You'll never know what real selectivity means till you take a turn at the Philco dial. This combination of Tone-Quality plus selectivity and range has been sought for years. Many radio sets heretofore either secured selectivity at the expense of tone or tone at the expense of selectivity, and most of them compromised between the two. Now, the combination of tone with selectivity and range has been achieved in the Philco Set. Radio's Greatest Achievements Combined This remarkable Philco Set is a product of the combined achievements of radio's greatest scientists. The Philco is licensed under the patents of The Radio Corporation of America, The General Electric Co., The Westinghouse Electric & Manufacturing Co., The American Telephone & Telegraph Co., Latour Corporation, Lowell & Dunmore, Hogan, and the Hazeltine Corporation. Then added to this are Philco's own discoveries by the Philco staff of engineers. Here is the Highboy of our complete line of Quality Furniture Models Designed by Hollingsworth-Pearce and Albert Carl Mowitz. Louis XVI period in the latest, most modern vogue — selected walnut panels, beautifully grained and superbly finished by expert cabinet makers. Includes Console Grand Speaker, Radio Receiver, Power Supply and Built-in Aerial. NO AERIAL Necessary— Therefore Movable —yes, the Philco Radio Set can easily be moved from room to room — merely plugging into the light socket. An aerial is not necessary to get perfect reception of local stations — and many distant stations. Special provision has been made for a portable ground. And if you decide to use an aerial, only twenty feet of wire in the room will bring you in stations from a remarkable distance. Longer aerials can be used to attain even greater results. All Electric — Entirely Dry The new Philco Set is an all-electric AC Radio receiver — merely plug it into the light socket and tune in. No batteries. Requires no water, acids or liquids of any kind. Entirely dry. (Continued on next page)
