A colleague at work wants to build a 200w hi-fi mono audio amp using a
pair of 811A's. Besides using a modified schematic of the ART-13
modulator (with modern and appropriate iron), anyone know of a design
book, etc. for high power audio tube amps? Surely someone out there
who's been buying VT-4Cs all these years will have an idea....hi!!
