English: As-built audio power amp schematic built around a diamond-buffer core, with Sziklai-type current boosters. This is my take on a classic 1987 circuit by V.Ageev, with modern parts and added output protection components. Practical output power from +/-40V rails: 75 WRMS into 8 Ohm (if the rails are stiff enough). The bootstrapped opamp has a gain of 3, and thus requires a full +/-12 Vpk input signal (another opamp).
Русский: Ядро УМЗЧ мощностью 75 Вт/канал (на 8 Ом при источнике питания +/-40В), построенного по мотивам схемы Агеева из Радио 2/87. Показано собственно ядро УМЗЧ + защитный обвес на выходе. Коэффициент усиления: 3, т.е. требуется ещё один каскад усиления с размахом +/- 12в пик-пик. |
