The input circuit of amplifier is a differential amplifier built around Q4 and Q5 that employ DC feedback thus preventing any DC voltage appearing across the speaker with the usual destructive results. Q11 acts as a current source and ensures that the input stage draws a constant current of 1 mA. Link [...] [...] The Circuit operates a symmetrical ± 40 VDC power supply and determines the maximum current of 2.6 A.
