RADIO AGE for October, 1927 43
Announcement
IN making a report on tests of a new seven-tube super-heterodyne which has been developed in the Radio Age laboratories our technical department brought in such good news about the circuit that we decided to pass it on to our readers. Full instructions on how to build the set, with illustrations, including blueprints, will be published exclusively in the November issue of this magazine.
1HE Quadrode (Four Element) Superheterodyne does not merely present something new and different in the arrangement of parts. It is not merely a modification of the reflex. It is not a reflex. It introduces an element into superheterodyne construction that has never before been used. This new method makes it possible to obtain power, selectivity and tonal quality equal to those of the best eight-tube sets. The fans will readily recognize the economy in time and effort and money in this elimination of one tube.
THE editors believe that this circuit will arouse the interest and eventually the enthusiasm of fans everywhere. Simplicity, compactness, excellent performance — those are characteristics sufficient to make the Quadrode popular, but it has that new feature which makes it an outstanding phase of this season's radio development.
