Speaker cabinet design is mysterious to most people, but it doesn't have to be - especially when it comes to speakers for musical instruments. Cabinet evolution is described culminating in Kevin's own designs built by London Power, based on 20+ years of experience and input from expert speaker designers. Resonant and non-resonant cabinets are explored, along with the choice for building materials, finishes, woodworking techniques, installing grill cloth, and the use of wheels and handles. Driver selection and mixing is detailed, covering driver impedance, power ratings and wiring.

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.

Building your own vacuum tube guitar or bass amplifier from scratch is truly an exciting experience. This book describes the detailed construction of five vacuum tube amplifiers.

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.

Gerald Weber, of Kendrick amplification fame, is the author of A Desktop Reference of Hip Vintage Guitar Amps and Tube Amp Talk for the Guitarists and tech. This is his third book, and works well as a companion to his previous books or on its own. 528 pages, softbound

New reprint of the 4th edition of this book, originally published in 1973. Discusses signal amplification theory, how each part functions in an amplifier and contains many schematics and amps popular at the time. Softbound, 382 pages. One of today's most popular instruments is the electric guitar. Proper operation of the amplifier associated with the guitar is essential to the amplification and enhancement of the guitar sound. The ultimate test of a guitar amplifier is the quality of the musical sound that comes from the speaker. Many electronic service shops hesitate to service guitar amplifiers because the service litarature is sometimes difficult to acquire through standard channels. Electric Guitar Amplifier Handbook has been written to dispel any qualms the serviceman may have about servicing these amplifiers. While explaining in detail the functions of all parts of the guitar, the author relates them to familiar electronic circuitry.
