  • A hi-fi stereo Class AB DC power amplifier with power output of 120 watts RMS per channel both channels driven into 4 ohms or 8 ohms. Direct-coupled Darlington parallel push-pull OCL pure complementary output circuitry, DC amplifier configuration, Class AB operation, toroidal power transformer, separate power supplies for (1) Dual FET, Differential and Pre-Driver stages, and (2) Power Output stage. Sophisticated protection circuitry. With Power switch, two Peak Power meters (0-240 watts), Protection indicator, Speaker switches A  B, and on the rear, two RCA phono inputs (Input Capacitor and Direct Coupling), terminals for 2 pairs of loudspeakers and a Ground connection.
