Performance 250t Appearance To the radio beginner, tubes are tubes. They all look very much alike. To him they may all seem very much alike if he has not yet learned how vital is the link be- tween tube performance and set performance. But with experience comes dis- crimination. He learns the value of aname, he comes to regard the name Cunningham as a pledge— never violated—of the Invisible Integrity in-built since 1915 into every radio tube that bears that name. This knowledge of Invisible Integrity— multiptied a million fold among radio enthusiasts—is the foundation of that Faith and Confidence in Cunningham Radio Tubes which has been more than ten years in the making. 4] It- All Types C-sCX~ In the Orange and Blue Carton CHICAQO - SAN PRANCTSCO 708 7th Street NORTHWEST 3123 M Street GEORGETOWN We Are Authorized Dealers nd—Pay On Light Bilt Main 10000 « Good Stock of RADIOLAS, TUBES and AC CESSORIES on 14th and C Streets NW.
