Books published by Career Professionals

Learn how to measure various parameters of hi-fi and guitar amplifiers & preamps: gain, input sensitivity, output power, harmonic and IM distortion, S/N ratio, crosstalk, input & output impedance, damping factor, frequency range, internal AC & DC voltages and waveforms, phono stage equalization accuracy and much more.

The only book exclusively dedicated to vacuum tube (valve) testers. Design, functionality, calibration and modifications of testers by B&K, Hickok, Triplett, Mercury, Sencore, Weston, Simpson, AVO, Taylor, RCA, Precise, Precision, Eico, Jackson, Sylvania, Knight, Heathkit, Seco, Sico, Conar, Metrix and other brands are covered in detail.

Guitar amp troubleshooting & repair, test & measurements, building (construction) of vacuum tube guitar amplifiers, it's all here. Dozens of tried & tested designs are featured, using both less common but great sounding tubes and much loved favorites such as EL84, 6V6, 6L6, EL34, and 7027A. A real treat for amp designers & DIY builders!

This unique manual explains how vacuum tubes (valves) work and how they are used in guitar amp circuits. Many examples of vintage & modern commercial amps serve as case studies to identify problems, fixes & improvements. With over 500+ photos and schematics, this practical book is a "must have" for guitar players, amplifier designers & builders!

Volume 3 of the most complete and practical modern reference on audiophile vacuum tube technology If you liked the practical side of Volumes 1 and 2, Volume 3 will delight you. No theory, just dozens of practical designs, proven circuits and useful test & measurement methods. Various directly-heated triodes are explored and used in line stages and power amplifiers, a true heaven for DHT lovers. Dozens of DIY and commercial amps and preamps with 2A3, 300B, VT25, #46, 12A, 201A, GM70, 805, 845, 813, 211A are described in detail, their circuits analyzed and improvements suggested. Most use no negative feedback and many feature interstage transformers or direct coupling. Many less known preamplifier and driver tubes are also explored and used in practical designs: EL33, 12B4A, EC8010, 6EM7, 6DN7, 6N30P, 5670, C3m, C3g and 1626 (VT-137). Most sound divine in preamplifiers and driver stages of power amplifiers! More than a dozen of vintage designs were discussed and analyzed, amplifiers that featured prominently in the history of hi-fi or are recommended as upgrade platforms, QUAD II, The Williamson amplifier, Dynaco MkIII, Quicksilver 8417 and Fisher SA-1000 among others. Designs by contemporary amplifier makers such as Audio Research, E.A.R., Shindo Labs, Leben, Jadis, Audion, Bel Canto, Marantz and others, also feature prominently in this volume. Valuable lessons can be learned from these case studies. Finally, for those who want proven, practical, ready-to-build designs, many of our own, tried & tested circuits are explained and analyzed. Most outperform expensive commercial audiophile gear by a wide margin. As an amateur DIY builder you are free to build them for your personal use, so just get your soldering iron ready and start building! This practical DIY manual is richly and professionally illustrated with photographs of tubes, components and amplifiers, circuit diagrams, tube pinouts, curves and loadlines, graphs and charts.

The most complete and practical modern reference on audiophile vacuum tube technology! Destined to become a true classic in its field, this unique DIY design & construction manual presents the theory and practice of amplifier design & construction in a balanced way. For those who dislike formulas and want proven, practical, ready-to-build designs, dozens of such commercial, tried & tested circuits are explained and analyzed. Just get your soldering iron ready and start building! Absolute beginners will benefit from the methodological approach, starting with DC circuits, then moving into AC voltages and currents and their circuits. The first few chapters of Volume 1 are a complete training course in fundamentals of electronics. Although the focus is on audiophile or "hi-fi" vacuum tube amplifiers, those interested in tube guitar amps will also benefit from the wealth of material presented, most of which directly applies to tube guitar amps as well. Apart from various audio circuits, electronic components, power supplies and tests & measurements are also covered in depth. Even tube testing and tube testers are discussed at great length, as is troubleshooting, repairing and modifying (upgrading) tube gear. The advanced topics that other books don''t even mention, such as audio transformer design, construction and testing, make this reference manual a valuable addition to your technical library. For those familiar with solid state devices, such as bipolar transistors and FETs, an easy and seamless transition into tube technology is provided in the book, which adopts a unifying approach to amplification and rectification devices, be they of solid state or vacuum tube kind. This practical DIY manual is richly and professionally illustrated with photographs of tubes, components and amplifiers, circuit diagrams, tube pinouts, curves and loadlines, graphs and charts. Hundreds of such valuable illustrations make it easy to comprehend issues. There is no need to search for, download and print such information, saving you valuable time.
