Baxandall and Self on Audio Power is the first Linear Audio issue that reprints classical papers. At 120 pages, the book is divided in three parts: Part I is a reprint of Peter Baxandall's Wireless World article series on audio power amplifier design from 1978/1979. Discusses everything concerned with feedback and stability. Part II is Douglas Self's WW series on power amp design from 1993/1994, concentrating on the various distortion mechanisms and how to minimize them, resulting in the Blameless Amplifier concept. Part III is a 35 page personal letter, never published before, from Peter Baxandall to Douglas Self commenting and expanding on Douglas' articles. A must read!

Articles in this Volume:


Audio Power Amplifier Design
Baxandall Peter

This is the classical series of articles that Peter Baxandall wrote for Wireless World in 1978 and 1979. The series consists of 6 articles, covering the following areas:
- Negative feedback concepts;
- Nyquist and Bode diagrams;
- More on feedback stability;
- Negative feedback and non-linear distortion;
- More on negative feedback and non-linear distortion.



Distortion in Power Amplifiers

This is the series of 8 articles Douglas Self wrote in 1993/1994 for Wireless World. The articles cover all possible sources of power amp distortion and how to minimize them. The resulting design came to ne known as the Blameless Amplifier, not because it was perfect, but because all distortions had been minimized as far as possible.
The series treats the following areas:
- The sources of distortion;
- The input stage;
- The voltage-amplifier stage;
- The power amplifier stages;
- Output stages;
- The remaining distortions;
- Frequency compensation and real designs;
- Class A amplifiers

Comments on distortion in Power Amplifiers

Baxandall Peter
In 1995, Peter Baxandall wrote a long (35 pages) personal letter to Douglas Self. In the letter, which has never been published before, Peter comments on Douglas' series of articles on power amplifier design. But more than just comments, he expands on the various issues, adds his own views and clarifies many issues in a very clear and concise manner. Thirty-five pages of typewritten text interspersed with hand-drawn graphs and schematics. A must-read jewel!
