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.
