Valve Amplifiers, Fourth Edition Review

: A new section in Chapter 1 specifically addressing charge amplifier design.

(2012) by Morgan Jones is a comprehensive reference for the design, construction, and maintenance of high-fidelity vacuum tube audio equipment. This edition expands on previous versions by shifting focus from distortion reduction to background noise reduction and introducing modern components like semiconductor constant current sources.
