A-I6' THE SUNDAY STAR, WASHINGTON, D. C, FEBRUARY 23, 1930—PART ONE. The Super-Heterodyne Circuit Proved Itself During the World War "~ TPor then, many thousands of lives were dependent upon the proper reception of signals even though they were broadcast under unfavorable conditions. Major Edwin Armstrong, United States Signal Corps, proved equal to the great task that confronted him by producing the SUPER-HETERODY! circuit for the allies.

Radios as fine as the Radiola 62 are not built in huge quantities—these were intended only for those people who appreciate and can afford the finer things in life. But, now they come to Lansburgh’s at a price that most any one can afford to pay. . ! This opportunity is confined to this store in Washington, for we bought the entire Washington allotment—to sell at a saving of $255.50 on each set, and when they are gone, there won't be any more. You've undoubtedly heard the RCA Radiola 62—if not, believe us, it-is marvel. ous! Tone as sweet and mellow as an old Stradivarius; supreme in distance getting and powerful in volume; super-selective; and as beautiful as fine cabinet making can produce.

Nine powerful “AC” Radiotrons are employed in Radiola 62, the receiving circuit of which consists of two stages of tuned radio freqeuncy amplification, first detector, oscillator, two stages of tuned intermediate frey amplification, a second power detector, and of power audio frequency amplification. Rec- i ion of the voltages for plate and grid throughout is accomplished by the ninth tube, Radiotron UX-280. Although Radiola 62 is super-selective, this desirable feature is accomplished without the loss of lity. The entire musical range of the broadcast signal by Radiola 62—yet each station is precisely 5 No other circuit is capable of this inclusive selectivity. The new RCA Dynamic Loudspeaker, an integral part of Radiola 62, incorporates refinements and improve- ments that are the results of extensive research work which hes been carried on for many years. It provi superior response over a greater number of musi octaves than have ever before been heard in radio re- ception. The remarkable performance capabilities of Radiole 62 end the obvious beauty and superior craftsmanship of its cabinet give to its justly proud owner a new econ- ception of Radio. the Radiola 62 America's depire for the really better things of life is, we believe, more keenly prominent at the seat of America’s Gov- ernment than elsewhere. oaie American thrift is practiced, we believe, more diligently within the District of Co- lumbia than elsewhere on this continent. oo AE 108 Thus, these deductions gave us courage to overlook the obvious and inspired us to accomplish the unusual in presenting the Radiola 62 at a phenomenally low price.
