Convention Paper

A Twenty-Five Watt High Quality Transistorized Audio Frequency Power Amplifier

Authors: Minton, Robert

AES Convention 10 · Paper 52 · September 1958

Abstract

This article describes the use of transistors in a high quality, audio frequency power amplifier. The amplifier, consisting of seven amplifying stages, is capable of delivering twenty-five watts of output power when driven by a variable reluctance magnetic pickup and operated from a -30 volt supply. It has low harmonic and intermodulation distortion and a good frequency response. The operating parameters of the transistors and the effective use of circuit stabilization assures satisfactory performance at ambient temperatures up to 55°C.
