TURN THE TRIMMER P1 TO OBTAIN ABOUT 7-10mV ON TIP142 EMITTER RESISTOR.
USE A 160VA TRANSFORMER (BEST 22-0-22 OR 24-0-24 VAC MAX.)FOR A STEREO VERSION .
the project is based on a Darlington TIP 142 and TIP 147 class AB amplification scheme, with complementary symmetry with pilot and input differential, powered by constant current generators
