Baxandall and Self on Audio Power: Linear Audio Classic
Baxandall and Self on Audio Power: Linear Audio
Arguably, the last quarter of the previous century saw audio (power) amplifier technology advance with great leaps. Active and passive components of great technical quality and reliability became available commercially. Detailed understanding of what exactly goes on inside our audio circuits, as well as the areas where improvements were possible, greatly increased. The original meaning of High Fidelity, i.e. trying to reproduce music from a source as transparent and as untouched as technically possible, was leading this advance. One important catalyzer for this progress was the British journal Wireless World, which published leading articles on audio technology. WW articles are to this day treasured and consulted by those interested in audio technology. Two often-quoted series of articles, written by Peter Baxandall and Douglas Self, have been reproduced in this book. In addition, some 35 typewritten pages by Peter, discussing technical amplifier issues, which never have been published before, have been added. Between them, Peter and Douglas treat the important issues in audio power amplifier design, Peter focusing on feedback and related issues, and Douglas focusing on distortion and related issues. Perhaps the most quoted (and most misunderstood) figure from Peter’s series w...

On the solid-state front, Kendall Castor-Perry designed a novel and ingenious gain-of-one power output stage that needs no adjustments or thermal compensation yet is extremely linear, even open loop. Our friend from Switzerland, Samuel Groner, came up with an equally high-performance push-pull transimpedance stage that could drive Kendall’s output stage, or any other, for that matter. Nelson Pass has a sequel to the Arch Nemesis, transplanting the SiC power device with a custom-designed Static Induction Transistor, the Pass SIT 1. Marcel van de Gevel describes a simple loudspeaker correction filter that gets away with standard value capacitors and a simple gain-of-one buffer amp as the active element. Patrick K (aka as EUVL), inspired by designs from Nelson Pass, Marshall Leach and others presents a minimalistic I/V converter for current output DACs based on jFETs and a floating power supply.
