This book contains most of the audio information on this site, and very much more- perhaps fifty times as much again. It is a unique collection of hard facts on audio amplifier design. The Fourth Edition adds more than 15% of new content. Yes, I'd love you to buy a copy. From any good/big bookshop, or via Butterworth. See link below:

This is a uniquely detailed guide to the theory and practice of audio power amplifiers, running from the elegantly simple mathematics of the differential pair to the practicalities of bolting down power transistors properly.
It includes the first complete explanation of the complex business of power amplifier distortion. It shows how the many sources of non-linearity can be eliminated or minimised, allowing amplifiers to be designed and constructed with performance that would have been thought impossible a few years ago. It provides information that is indispensable whether you are making one amplifier for the ultimate home system, or setting up a production line to make 10,000 units a year.
