In Reply to: What PP amp to build? posted by speleo on April 2, 2007 at 06:47:34:
Using Allen Wrights schematic as a starting point. El34's, 6550/KT88/KT90, and 300B are all possible options for output tubes depending on desired power/sound (even 2A3 choke input supply for lower B+). There are other tubes that can work for the front end if you dislike the 6922.
