Theory okay, but needs updating
on 24 July 2011
The theory in this book is sound and is understandable. The author presents his designs well, and if you have a good knowledge of analog electronics it is easy to follow. The reason I only give two stars is that the book shows its age by using obsolete components and ignoring more modern technologies like the latest ultra low noise op-amps and newer components which make Class D and Class Z amplifiers comparable to the designs presented in this book. Readers looking to use this book as a source of ready-to-build projects may be disappointed. I found that many of the semiconductors used in the designs presented in the book are no longer available - or at least only through suppliers stocking used parts or surplus. When you start scouring the data sheets for modern equivalents, it becomes obvious that more modern devices with better specs are now available, and again the book shows its age.
