The Ultimate Tone, Volume 4, Advanced Methods for Amp Design
by Kevin O'ConnorOutlines, in schematic form, many approaches that achieve the goal of power scaling, super scaling and power management. A complete history and discourse on the technology outlines how to implement multiple power scale controls, alternative circuit forms and system impacts. Further tutorials outline the methods for super scaling, with both fixed and variable boost ratios, using both solid-state and tube methods.
The Ultimate Tone, Volume 6, Timeless Tone Built for the Future
by Kevin O'ConnorThe evolution of guitar amp circuits becomes a revolution! TUT6 takes you through advanced DC Power Scaling methods; reveals the secrets of Dumble amps; explores the truth about high-gain preamps; demonstrates how to build Z-B-X push-pull power amps with a single power tube; simplifies the design of 400W+ tube amps - methods that can be applied to any power level; presents class-G tube amps where 100W of output has the same waste heat as a 25W amp; explores modern mains control and sustain circuitry. 312 Pages, 404 figures, spiral bound, 9" x 11"

Guitar Amplifier Electronics Basic Theory
by Richard KuehnelThis book presents vacuum tube amplifier theory using modern, web-based design tools and computer visualizations to eliminate the usual litany of mathematical formulas. The book begins with the fundamentals of electronics and vacuum tubes. It then proceeds through each stage of a modern guitar amplifier, including preamp voltage amplification stages, cathode followers, tone stacks, power amps, phase inverters, and power supplies. The final chapter is devoted to the craft of controlling overdrive dynamics and harmonic distortion.
Tube Lore II, A Reference for Users and Collectors, 2nd Edition
The classic Ludwell Sibley book is now available in this wonderful second edition. Tube Lore II contains a wealth of knowledge and information on a wide variety of tube types. Any tube collector or radio aficionado will find the contents of this book to be an invaluable reference.
Guitar Amplifier Electronics: Circuit Simulation
This book is a step-by-step tutorial for simulating vacuum tube guitar amplifiers using LTspice, a free SPICE-based electronic circuit simulator for Windows and macOS. The book walks you through the basics of developing a schematic, setting up a simulation, integrating vacuum tube models, and interpreting the results. From there it gradually ramps up to advanced topics, like verifying the sonic performance of a guitar amplifier as a complete system, analyzing the dynamics of overdrive, and writing new SPICE models for triodes and power tubes.
Fundamentals of Guitar Amplifier System Design
Books about guitar amplifier electronics usually focus on individual circuits: preamp stages, tone stacks, phase inverters, the power amp, and power supply. Fundamentals of Guitar Amplifier System Design presents a structured, top-down approach to crafting a complete guitar amplifier.
