Although it is true that accurately calculating electronic circuits can involve complicated formulas, for the electronic hobbyist it is not necessary to perform at the level of an electrical engineer. With some basic knowledge it is possible for the hobbyist to design and build vacuum tube audio amplifiers that perform well. This book covers basic electronics related to vacuum tube amplifiers, an elementary guide for understanding and working with vacuum tube amplifier circuits. Sections cover electronic and audio information that are concise with many examples and illustrations. Vacuum tube amplifying circuits are explained in simple terms without complicated math. Math is primarily basic math and a few simple formulas all solvable with a standard calculator and presented with examples. A table of component values for the popular 12AX7 in various operating parameters simplifies amplifier stage design. The first section of the book contains more detailed technical basic electronic information. Sections two through four are more casual in presentation and include pertinent information from section one. Included in this book are eight project circuits with parts list and component layouts for a Buffer Line Amplifier with 25db gain, 6V6SE Monoblock Amplifier, Triode Balanced/Unbalanced Input, Tone Control Stage, Cathode Follower Output, and Turntable Pre-Amplifier. Also included are a 6V6SE Stereo Amplifier and Guitar Amplifier project circuits with component layouts.

This book is a beginner's guide that brings you, from the basic concepts of vacuum tubes, up to the design of a complete integrated push-pull vacuum tube amplifier.This book first introduces the needed principles, to designing and understanding vacuum tube amplifiers. Then, it considers all relevant aspects for designing an integrated push-pull vacuum tube amplifier, including the power supply unit. Finally, a real integrated push-pull vacuum tube amplifier is designed from scratch, using the various concepts discussed in this book.This book makes an extensive use of figures and proposes several practical examples, to design various parts of the circuits and to compute values of the needed components. This significantly contributes to simplify some possibly difficult concepts addressed.The book is structured as follows: Chapter 1: "Introduction" introduces the book itself and gives some suggestions on how to read it.Chapter 2: "Vacuum tube basics" introduces the needed concepts to understand vacuum tubes. This is a very basic introduction needed for the non-initiated. If you already know what vacuum tubes are and how they operate, you can skip this chapter.Chapter 3: "Vacuum tubes as amplifiers" discusses how vacuum tubes can be used to obtain an amplifier. It introduces the concepts of operating conditions, loadline, biasing techniques, and amplifier classes.Chapter 4: "Integrated push-pull vacuum tube amplifier" goes into the details of designing an integrated push-pull vacuum tube amplifier. It discusses the single-ended and push-pull configurations, the various needed stages (power, phase-split, and input stages), and global negative feedback.Chapter 5: "Power supply unit" discusses how to build the power supply unit for a vacuum tube amplifier. It introduces rectifier configurations and filters to reduce voltage ripple, to have a quiet amplifier. It explains how to estimate expected output DC voltage, ripple, and current delivered. It also discusses how to design power supply for the fixed bias circuit and for the filaments of the vacuum tubes.Finally, Chapter 6: "Step by step design of a push-pull tube amplifier" use all needed notions to design an entire integrated push pull vacuum tube amplifiers. It discuss the design of the power stage, the phase-split, and the input stage. It discusses the design of the global negative feedback loop. It also provides the design of the corresponding power supply unit

In the second edition of Electronics for Guitarists author Denton Dailey teaches the basic theory of operation and design principles of analog guitar signal processing circuits and amplifiers. The design and operation of common effects circuits such as tone controls, preamps, phasers, flangers, envelope followers, distortion and overdrives are covered, as are both solid-state amplifiers and power supplies. Written primarily for the guitarist, this book balances coverage of theoretical analysis and design while providing many examples of practical experimental circuits. The main thrust of the material is analog circuitry, focusing on fundamental principles of transistors, integrated circuit and vacuum tube-based amplifier operation and theory, and operation of typical guitar signal processing effects circuits. Updated to the new edition include: • New coverage of tone control circuits, MOSFETS and their applications as small-signal amplifiers, rail splitters and charge pumps, amplifiers using germanium transistors, and tube power amp design • Expanded coverage of numerous subjects such as vacuum tube power supplies, the digital oscilloscope, Darlington and Sziklai transistors, and signal spectra and transfer function symmetry • Additional examples of various circuits such as overdrive, distortion, chorus, delay, tremolo and auto-wah circuits as well as amplifier design Electronics for Guitarists is ideal for the musician or engineer interested in analog signal processing. The material is also useful to general electronics hobbyists, technologists and engineers with an interest in guitar and music-related electronics applications.

This text offers a comprehensive introduction to a wide, relevant array of topics in analog electronics. It is intended for students pursuing courses in electrical, electronics, computer, and related engineering disciplines. Beginning with a review of linear circuit theory and basic electronic devices, the text moves on to present a detailed, practical understanding of many analog integrated circuits. The most commonly used analog IC to build practical circuits is the operational amplifier or op-amp. Its characteristics, basic configurations and applications in the linear and nonlinear circuits are explained. Modern electronic systems employ signal generators, analog filters, voltage regulators, power amplifiers, high frequency amplifiers and data converters. Commencing with the theory, the design of these building blocks is thoroughly covered using integrated circuits. The development of microelectronics technology has led to a parallel growth in the field of Micro-electromechanical Systems (MEMS) and Nano-electromechanical Systems (NEMS). The IC sensors for different energy forms with their applications in MEMS components are introduced in the concluding chapter. Several computer-based simulations of electronic circuits using PSPICE are presented in each chapter. These examples together with an introduction to PSPICE in an Appendix provide a thorough coverage of this simulation tool that fully integrates with the material of each chapter. The end-of-chapter problems allow students to test their comprehension of key concepts. The answers to these problems are also given.
