A Signal Biasing Output Transformerless Transistor Power Amplifier

Present techniques for the design of power amplifiers, whether transistor or vacuum tube, rely upon optimizing performance for pure resistive termination. While this leads to a high degree of compatibility among amplifier specifications and allows quantitative comparison between amplifiers, it does not assure that amplifiers of similar or identical specifications will sound alike when loaded by the same loudspeaker system. It is also axiomatic that subjective excellence with loudspeaker termination requires more costly amplifier construction than less transparent sounding units. By attacking the design of a power amplifier from considerations of the loudspeaker loads that it may be called upon to drive, we shall demonstrate that a good quality amplifier may be constructed from a minimum of components and with an extreme amount of reliability.
