Linear Audio Vol 6: High-Quality Audio Engineering Journal | Perfect for Audiophiles & Sound Engineers

Linear Audio Vol 6 is the seventh issue of a series of printed bookzines dedicated to technical audio and perception.Guest Editorial:David Zan is preparing to write about Advanced audio power amplifiers in a future issue – in this Guest Editorial he explains his reasoning and what he means by ‘Advanced’. Tutorials:Bob Cordell explains his own perspective on Advanced Amplifier concepts in TPC and TMC Feedback Compensation for Power Amplifiers. Robert Munnig Schmidt is back with Fine-tuning and measurements of a sensorless motional feedback subwoofer. In RIAA Revisited, or how to better judge documented figures, Hans Polak reconciles phono preamp specifications that often excel in data that cannot be compared between units. In his Introduction to noise Ronald Quan provides a nice, clear overview of noise issues in circuit design. Circuit design:Frank Blöhbaum shows that you can use an unseemly collection of exotic vacuum devices to make great Multiplied Transconductance Amplifiers. Diehard Erno Borbely teamed up again with Sigurd Ruschkowski to design Proteus – a current input moving coil preamp*. In contrast, Hannes Allmaier went back to Peter Walker’s 3-transistor design and morphed it into The High-Octane phono preamp. Daniel Joffe tried his hand – successfully – at Practical Electronic Control of Class AB Output Stage Quiescent Current.Simulation and modeling:Michael Rothacher, no newcomer to SITs, developed A Concise Model for Static Induction Transistor IV Characteristics which you can use with any Spice-compatible simulator.Speaker Design:If you ever wondered How to design a winning, blind-preferred loudspeaker – David Moran tells all.The Way I see it…Our columnist Stan Curtis notes that The map is not the world and reviews what can go wrong from your wonderful prototype to a real-world product. Book review:Jean Pierre Vanderreydt reviews Douglas Self’s latest tome, Audio Power Amplifier Design, 6th edition, and likes what he reads.Enjoy another issue packed with creative, innovative and thought-provoking articles!Jan Didden, Publisher/Managing Editor
