process of the amplifier, and a high technical indicators circuit, is an excellent high-fidelity power discharge path. VTi for the input stage, the use of a PNP transistor input stage and both impedance matching function, VTz voltage amplification stage and both CE and inverted push function, VT3 and VT4 constitute complementary push-pull amplifier output stage O R7, and R Pat negative feedback loop and determine the circuit gain: Av-R7 cuddle 8-2.7/0.22, together 21dBo bootstrap capacitor C3, R6 for the isolation resistance.
