[QUOTE="MusicMan_ZA, post: 1066219, member: 14924"] I am looking to start building a push-pull Class AB EL84 stereo valve amp soon. I have the input transformer(s) and two EL84 output transformers. I have come across the Il Terzo by Giuseppe Amato, and I like his approach and design. It all seems clear and simple (well thought out, and well explained in his book) and the schematic is available, as is the parts list. I have the required valves, so all good there, too. [url=https://www.vtadiy.com/home/tube-amplifiers/il-terzo-12ax7-el84/]https://www.vtadiy.com/home/tube-amplifiers/il-terzo-12ax7-el84/[/url] The only issue (so far) is that my OPT do not have 40% taps, so I cannot build it in an "Ultra Linear" configuration - correct? So my first question is, what is the way around building this design, but not as UL? Secondly - any other thoughts on this design? Any reason I should NOT build it? Thirdly - if not, which design should I consider? Lastly - any other advice? [/QUOTE]
