Tubes and Circuits, is the most comprehensive and up to date text on vacuum tube audio currently available. Join Transcendent Sound's Bruce Rozenblit as he takes the reader on a journey from the basics up through advanced designs. Vacuum tube operation is completely explained from the chemistry of tubes through the electric fields that control them, how they work and how they fail. Essentials of DC and AC circuits are covered as well as some of the most useful circuits in tube audio. Single-ended and push-pull transformer output stage theory is also presented.
