New: The Lux91 MonoMax

New article: The Lux91 MonoMax, the 300B single-ended monoblocks I designed for DIY HiFi Supply in Hong Kong. A Western Electric 91 gain stage with a 310A, my reactive interstage, fixed bias by an active bias module and an all-film-capacitor supply: 16 W from one 300B, and overload that never turns hard. With the original schematics and pictures from the 2010 manual. It is the third entry under Designs.
