Circuit Notes:
Distortion is much less than 0.1% up to 100HZ and increases to about 1% at 20kHz.50V CT transformer might be difficult to find, you may use 45V or 32V CT transformer.Q1 and Q2 should be use heatsinks to prevent over heating.50W Amplifier Circuit based ICL8063 + 2N3055 source page Advertisement:
