I'm trying to get my head around this circuit, the dual power supplies are throwing me off a bit. I need to find component values, showing calculations from a DC and AC viewpoint in order to get a 14dB voltage gain with 20W output power, and greater than 2k input resistance.
Am I correct in saying that Q1 is driving the push-pull configured Q2 and Q3? If I need a 14dB voltage gain (5), would I get that from Q1, since the gain from Q2 and Q3 will be 1. Does this circuit have a particular name? I can't find any examples to help me with understanding the circuit operation.
