Linear Audio has published Volume 2, the third in their series of books on tech audio.


Vol. 2 again presents a wide variety of technologies and subjects. Bob Cordell is back with a very high quality KT-88-based tube power amplifier, while Rudolf Moers covers an ultra-linear adventure. Rudolf’s book Fundamental Amplifier Techniques with Electron Tubes, published by Elektor, is reviewed by Guido Tent and gets high marks. If there was ever anything you wanted to know about the design, advantages and trade-offs in ultra-linear tube (ULT) power amps, this article is sure to answer it. Another review discusses Douglas Self’s latest book The Design of Active Crossovers.


On the solid-state front, Kendall Castor-Perry presents his design for a novel and ingenious unity gain power output stage that needs no adjustments or thermal compensation yet is extremely linear, even open-loop.


Samuel Groner from Switzerland describes an equally high-performance push-pull transimpedance stage. 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 with standard capacitor values and a buffer amp. EUVL presents a minimalistic I/V converter for current output DACs based on jFETs and a floating power supply. Stuart Yaniger shares some interesting insights and experiences related to controlled listening tests.


Gary Galo’s Guest Editorial provides a thought-provoking insight into the history, development and current state of digital audio.


Several of the articles in Linear Audio Vol. 2 can be used as construction projects, like the tube and power amplifier articles or the I/V converter articles.
