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
The high current of these little monsters is immediately felt, with an exuberant character and with a crystalline and precise sound they are certainly suitable for those who love energetic sound.
They pilot everything with a really good performance
