Where to buy:
Designing High-Fidelity Tube Preamps is a comprehensive guide to the design of small-signal, tube-based amplifiers.
This book examines in unprecidented detail the inner workings and practical design of small signal stages,
volume and tone controls, RIAA equalisation, power supplies and more.
Aimed at intermediate to advanced-level hobbyists and professionals it teaches the principles of low-noise,
low-distortion tube design, through easy-to-read explanations and minimal math. With over 400 diagrams and figures,
and hundreds of real measurements of real circuits, it asserts itself as an essential handbook for any tube amp enthusiast.

In fig. 1.56 the output sinewaves should appear inverted.
On page 96 it should read:
"Since the turns ratio is 4, the voltage gain should be 12dB..."
On page 101 it should read:
"Fortunately the space charge is negatve and neutralises such ions..."
On page 221/222 the bullet point list should read:
"Possible noise advantage when used with high-ra triodes.
Poorer signal-to-noise ratio when used with low-ra triodes."
