I am trying to build a simple three stage audio amplifier, as shown in the attached schematic. The problem I am running into is that my prototype is giving significantly different results than my simulation.
I am trying to drive 4ohm speakers, and have at least a maximum gain of 15, though slightly higher would be better. When I test my prototype the maximum gain I can get is about 13, rather than the 21 the simulation shows. Also, the prototype has much more distortion than the simulation.
I was wondering if someone else had experience with this sort of thing and could point me in the right direction.
