Could do better
, 2 Dec. 2004
This review is from: Aspen Pittman: The Tube Amp Book (Spiral-bound)
This book contains a large number of useful schematics and some excellent photographs of rare vintage amps; however, these are really the only reasons for buying this book. The summary of valve amp manufacturers is useful too. The rest of the book consists of advertorial for Groove Tubes products, and a number of "technical" articles, most (but not all) of which contain serious flaws. For example "filter capacitors are not in the audio path" and my favoraite piece of twaddle "valve shields confuse your electrons"!! The author of this gem even copied this almost verbatim from another article. This is not an authorative discourse on valve amps. Buy this for the pictures.
