MJR7-Mk3 Mosfet Audio Power Amplifier 70W output power at 60v The Electronics Schematic Diagram MJR7-Mk3 Mosfet MJR6 page includes distortion extracted using the nulling method with a speaker load and a music signal to demonstrate that these designs have no audible distortion in normal use. The MJR7 has even lower distortion, for example the 19kHz […]
