There is something here for every audiophile.

His Book (in its fourth printing)
Introduction to Electro-acoustics and Audio Amplifier Design, Third Edition

If you are a serious advocate of matters acoustic, the read/study will be well worth the effort.
A little math is required, but it is not at the 'daunting' level.

:) Hmmm, Great!; in 1978 I started to build His amplifier, which came on 2 issues of Audio Mag., between my then partner and I managed to build 1 side, and it worked great, but We got involved in different projects and sold the parts to some guy I never seen since; Wonder if it was ever finished; At that time, it was a bitch to get the parts, and We wound the pretty HD transformer by hand, I do not remember the gauge of the secondary, but it was tough.
