I have been looking at two-stage audio amplifier circuits and running them in LTSpice.
When I look at the output graph, the output voltage is always riding on a dc level despite the coupling capacitors. The problem, whatever it is, is in the 2nd stage. In the real world I can see this happening if you if a leaky coupling capacitor but in a simulation? I have tried many versions with the same result each time. Any ideas on
why this might be happening?
