I am an old fellow, a buider.... 50 years building power amplifiers..only audio amplifiers...i have 59 years old.... skilled in practice, burning fingers, doing things, listening and testing, inspecting using scope, using simulators and buiding a lot...one each day...more than 5000 amplifiers built...to listen, to evaluate, to compare and to dismount.
I am not an engineer, not someone addicted to theories....i love and respect the ones do things.
regards,
Carlos
