Westinghouse 50 kw Transmitter • Surge-proof. • Withstand heavy overloads for short periods. • Require no complicated relaying. • Can be connected to power circuit instantly without time for heating up. • Have unlimited life. These rectifier units are newly developed for radio application by Westinghouse — pioneer in commercial broadcasting. They are highly efficient, super-reliable. They are used throughout— except for main high voltage rectifier. Bias rectifiers for speech, the input stages, power amplifier and modulator, as well as plate rectifiers for the exciter unit are all of this type. From this and other sweeping improvements have come the new compactness, over-all efficiency, modern streamlined appearance, and similar advantages which make the Westinghouse Type HG transmitter distinctive. A new circuit principle, developed by Westinghouse, results in an efficiency of 80% in the power amplifier alone — more than twice the plate efficiency of conventional circuits and at least 20% ahead of other equipment now available. Your nearest Westinghouse office can give you complete details covering the operating advantages listed at the left. • • • Tune in Thursday nights to "Musical Americana," with Westinghouse Radio Orchestra, 100 Men of Melody and Swing Choir . . .
