from the "old days" but much of what was true then is true now.
A good read frpom the start but of particular interest are chapters nine up which deal with tube amplifier theory and acoustics.

Oldy but a goodie and like i said still valid information there -plus it is just flat out fun to see how far "the movies" have come
