This book of amp schematics was assembled with service and repair in mind. I have always had a very deep respect for the design and performance that tube amps produce. Let's face it, guitar tube amps don't always get the respect that they deserve. Tube amplifiers have always worked hard and should be looked at as a major part of your sound as they inspire you to dig deep into your playing. If you feel somewhat the same way I do about tube amps, then you know each amplifier has their own characteristics and tone. I hope you can use this educational information to understand how tube amps are designed and how they work.
(Book). If you have questions about guitar amplifiers-how to fix them, how to restore them, or how to hot-rod them-this book has the answer. This book is written for the guitarist or collector who desires a common sense approach to understanding the essence of vintage tube amps and vintage tube tone. Not written for engineers, it does not contain engineering formulas, polar mathematic equations, or abbreviations that are assumed you should know. Gerald Weber, a regular columnist for Vintage Guitar magazine, shares the knowledge he has accumulated over the years of repairing and building his line of Kendrick amps.
The operational amplifier ("op amp") is the most versatile and widely used type of analog IC, used in audio and voltage amplifiers, signal conditioners, signal converters, oscillators, and analog computing systems. Almost every electronic device uses at least one op amp. This book is Texas Instruments' complete professional-level tutorial and reference to operational amplifier theory and applications. Among the topics covered are basic op amp physics (including reviews of current and voltage division, Thevenin's theorem, and transistor models), idealized op amp operation and configuration, feedback theory and methods, single and dual supply operation, understanding op amp parameters, minimizing noise in op amp circuits, and practical applications such as instrumentation amplifiers, signal conditioning, oscillators, active filters, load and level conversions, and analog computing. There is also extensive coverage of circuit construction techniques, including circuit board design, grounding, input and output isolation, using decoupling capacitors, and frequency characteristics of passive components. The material in this book is applicable to all op amp ICs from all manufacturers, not just TI. Unlike textbook treatments of op amp theory that tend to focus on idealized op amp models and configuration, this title uses idealized models only when necessary to explain op amp theory. The bulk of this book is on real-world op amps and their applications; considerations such as thermal effects, circuit noise, circuit buffering, selection of appropriate op amps for a given application, and unexpected effects in passive components are all discussed in detail. *Published in conjunction with Texas Instruments *A single volume, professional-level guide to op amp theory and applications *Covers circuit board layout techniques for manufacturing op amp circuits.
Most musicians would like to understand how their amplifiers work. For reason to either get a better tone, explain that tone to their serviceman, prevent an amplifier from failing on stage, perform a quick-fix on the job, do their own maintenance, maybe even start their own repair or custom amp business. This book is intended to provide an actual Workbook that can be opened up on your workbench and used to study, service, or modify tube amps. The book is laid out in a "cadence" of schematic on top, with the appropriate layout underneath. This allows you to see both drawings at the same time. It also means that some pages are intentionally left blank, so as to not break the "cadence." These pages can be used for note taking. After all, this book is meant to be used. Contained in the chapters are reference pages for Jensen Speakers, Fender Transformers, and Accutronics Reverbs.
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. All the information required to design and build tube amplifiers is compiled in one place. Who is this book for? Audiophiles and guitar players wanting to learn how tubes and tube amplifiers work. DIY constructors who wish to take their knowledge and building skills to a higher level. Buyers and sellers of tubes and tube equipment who need a better understanding of tube technology. Electronic technicians and engineers familiar with solid state devices and circuits, who want to expand their knowledge of tubes and their circuits. Anyone who wants to learn how to design, build, test, fix, or upgrade tube gear.

Building Valve Amplifiers is a unique hands-on guide for anyone working with tube audio equipment--as an electronics hobbyist, audiophile or audio engineer. This 2nd Edition builds on the success of the first with technology and technique revisions throughout and, significantly, a major new self-build project, worked through step-by-step, which puts into practice the principles and techniques introduced throughout the book. Particular attention has been paid to answering questions commonly asked by newcomers to the world of the valve, whether audio enthusiasts tackling their first build or more experienced amplifier designers seeking to learn about the design principles and trade-offs of "glass audio." Safety considerations are always to the fore, and the practical side of this book is reinforced by numerous clear illustrations throughout. The only hands-on approach to building valve and tube amps--classic and modern--with a minimum of theory Design, construction, fault-finding, and testing are all illustrated by step-by-step examples, enabling readers to clearly understand the content and succeed in their own projects Includes a complete self-build amplifier project, putting into practice the key techniques introduced throughout the book
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!
