摘要

新型功率晶体管的发展使高性能音频放大器的制造成为可能,其性能可与目前最好的真空管放大器相媲美。讨论了采用RCA漂移场功率晶体管的放大器的设计、结构和性能特点。该放大器能够提供50瓦的功率输出,失真小于0.5%,从20周期到20,000周期。还讨论了一个5瓦的a类放大器和一个15瓦的每通道立体声放大器,结合了高性能和经济性。

An Ultra-Low-Distortion Transistorized Power Amplifier
The development of a new type of power transistor has made possible the construction of ultra-high-performance audio-frequency amplifiers which can equal the performance of the finest vacuum-tube amplifiers available. The design, construction, and performance characteristics of such an amplifier, using RCA drift-field power transistors, is discussed. The amplifier is capable of providing a power output of 50 watts at less than one-half per cent distortion from 20 cycles to 20,000 cycles. Also discussed are a five-watt class A amplifier and a 15-watt-per-channel stereo amplifier which combine high performance with economy.
