Linear Audio 9 is the tenth volume in a series of bookzines dedicated to audio technology and perception. Linear Audio offers a variety of articles written by an international team of authors and accredited academics on a plethora of engaging subjects, from tutorials to circuit and system design, test reports and book reviews.Compiled by Jan Didden, also audioXpress technical editor, the Linear Audio bookzines are a vehicle for publishing technical information, developments and the state of the art of audio from a technical perspective. As Jan Didden explains, “the goal is to provide an outlet for authors to write about their accomplishments and projects, and to provide a technical audio resource for those interested.”
In this Volume 9, John Escallier discusses semiconductor junction dissipation and temperature using theory and practice for a reliable design. John Vanderkooy teamed up with Kevin Krauel and Todd Schneider to design A Low Parts Count Audiophile Power Amplifier. Stan Curtis mulls over the strengths and weaknesses of class D. And if you are interested in testing several phono preamp topologies and device choices, Burkhard Vogel’s The RIAA Phono- Amp Engine II provides the perfect testbed and comparison setup.
There’s also an interesting article by Rudy van Stratum, “A short history of advertising in audio”, complemented with the second part of Giovanni Stochino compilation on feedback and feed-forward error correction. Jan Didden himself writes about thermal transient variation of power amp quiescent current –
Instrumentation and findings. As he explains,”Yes, it exists; and no, it doesn’t hurt.”
Cyril Bateman’s article series on ‘capacitor sound’ in Electronics World needed to be updated with new insights and parts, after more than a decade. Capacitor sound revisited – Distortion mechanisms behind the sound of Wound and Stacked Capacitors tells all.
Bob Cordell, a very experienced user of Linear Technology’s LTspice simulator, reviews Gilles Brocart’s The LTSPICE IV Simulator – Manual, Methods and Applications and wished he’d had it years ago. Douglas Self’s Small Signal Audio Design is already in its 2nd edition; Jean-Pierre Vanderreydt gives it a thorough review, and likes what he reads.
