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.
$39.95 Tonnes of Tone, Electronics Projects for Guitar and Bass by Kevin O'Connor A collection of projects for electric guitar and bass players.

The "experimenters power supply" is excellent for tinkering with tube circuits, containing separate AC heater, DC heater plate and bias supplies. Build a wide range of tremolo circuit and an all-tube reverb unit. Circuit operation, construction, & layout guidelines are provided. Every project uses easy to find parts.$37.00
Electric Guitar Amplifier Handbook, fourth edition
by Jack Darr
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.
