  • Designed to provide the utmost in performance at a reasonable price. Suitable for any public address installation. Uses 2—’27 or ’56, 2—245 and 1—280. Essential flat frequency response on voice and music, thus assuring high quality reproduction for any purpose. May be adapted to any form of installation, including inter-communication, microphone, or radio pickup. Due to the high gain circuit used in these amplifiers it is possible to obtain the full output of the tubes used with any form of input. Input connects direct to grid of tube, is of high impedance which permits the amplifier to be coupled to one or more magnetic speakers, or to three or four dynamic speakers which have their own output transformer. It is possible to operate the amplifier from any auto A.C. power unit delivering 65 watts or more, to make an inexpensive sound truck system. Conservatively rated for constant use.
