B-932 The Ultimate Tone, Volume 4, Advanced Methods for Amp Design
by Kevin O'Connor
Outlines, 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.

B-695 The Ultimate Tone, Volume 1, Modifying & Building Tube Amps
by Kevin O'Connor
This is the book that jump-started the boutique tube guitar amp business. Learn the truth about tube preamp design and modification; see how tube power amps work and can be made more reliable; see how reverbs and effects loops work and better ways to configure them; learn why some amp brands are easier to service and to mod than others; see how simple switching circuits are but how capable they can be. Tube data for the common types used in guitar and bass amps is provided, along with a discussion of stage set-up and player ergonomics. Spiral bound, 395 figures. 368 pages, 2.5 lbs, 8.5" x 11"

B-891 The Ultimate Tone, Volume 3, Generations of Tone
by Kevin O'Connor
Have you ever wondered if there is a better way to build a Bassman, Champ, Plexi, an 800, AC-30, Bulldog or Portaflex? Or you wanted to build an SVT with off-the-shelf parts? How about a master-volume amp that doesn't change tone with the master setting? Everything you need to know is right here, including: proper grounding techniques, wiring methods, and mechanical considerations. Eighteen chapters cover the "iconic" amps everyone knows and loves, with schematics and layouts for each, along with the technical history of the product.

B-913 The Ultimate Tone, Volume 5, Tone Capture
by Kevin O'Connor
Every part of your system contributes to your Ultimate Tone, so every part is important. The Ultimate Tone, Volume 5 delineates, in clear language, the function of each electronic component in a circuit, and how alterations to the value of each part affect the final sound. Gain stage voicing, interstage attenuator optimization, sustain restoration for clean and distorted tones, power amp and preamp "tone generators", simple boost pedals, amp selectors and power conditioners are all covered, with designs using off-the-shelf parts. Like TUT3, this is a "project book" presenting design challenges and solutions, with a diversity of tube and solid-state circuits for bass, guitar and keyboards.

B-726 Principles of Power, A Practical Guide to Tube Amplifier Design
by Kevin O'Connor
This book offers a simplified method for designing tube power amps for audio. Tube operation is explained, as are circuit principles. Class-A or B, cathode, fixed bias, and push-pull and single-ended designs are covered, as are many front-end circuits. Includes designs using off-the-shelf transformers and current production tubes. Power outputs of 15 to 400W are depicted using pentodes and true triodes. Also, covers power supplies, selected tube data, and information on Hammond and Plitron transformers. Guitar amp builders please refer to "The Ultimate Tone Vol. 2"

B-947 Vacuum Tube Circuit Design: Guitar Amplifier Power Amps
by Richard Kuehnel
The power amp transforms the carefully crafted signal voltages served up by the preamp stages into the punch and sizzle that defines a guitar amplifier's character. It is in the power stage that the designer orchestrates the nuances of touch and tone in an environment of vacuum tubes and circuit components being pushed to their limits.
Guitar Amplifier Power Amps moves beyond simplistic advice to present a complete guide to the theory and operation of single-ended and push-pull power amplification. From the phase inverter input to the loudspeaker output, every aspect of circuit design is rigorously explained and thoroughly explored. Find out what happens when Class A1 and Class AB1 circuits are overdriven to distortion levels never imagined by Frederick Terman or the Radiotron Designer's Handbook.

B-957 The Fender® Bassman 5F6-A, 3rd Edition
by Richard Kuehnel
This book examines this famous amplifier by studying its circuit design in great detail. It starts by breaking the amplifier into its major components: the 12AY7 preamp, the 12AX7 voltage amp, the 12AX7 cathode follower, the tone stack, the long-tailed-pair phase splitter, the push-pull power amplifier, and the power supply. Each component is analyzed to determine how it works and to derive the design formulas needed to predict its performance. The results are then compared to bench tests of the actual circuit. Finally all of the components are put together to analyze total system behavior and to discover how and where the amp transitions into distortion.
