hey..i have to design an audio amplifier with a gain of around 3600V/V (load is a 10W, 4ohm speaker and input is 5mV(p-p) i have designed two stages and cascaded them for this gain (attached)..nw i have to design the output stage using class AB type biasing it with Vbe multiplier (using tip31c and tip32c transistors)...i designed one bt the gain drops remarkably wen i cascade it..hw shud i bias it so that the gain does not drop??
