Hi all.
I´m new in this forum and is my 1º post. In 1988, i build my 3º amplifier (50W). The amplifier is class B, had differential input, no Miller cap, double bootstrapping and quasi-complementary design. I want to build a newer amplifier, or no. My questions 1º, What is your think about the attached schematic amplifier. 2º, I modify my amplifier, or build a new amplifier ( P3A.......) I need your help. Thanks Guillermo Eirin |

R2/C2 is a classical RC, in my opinion the better alternative for feedbackcompensation than cdoms. Mike |
