3 stages power amplifier project
Zero999:
Your circuit is far too dependant on the hFE of Q2 to be stable. Every time you change something slightly, the voltage gain of Q2 will change and mess everything up.
Lucky-Luka:
I still have to implement the input stage and the final feedback.
I was adding a stage after the other as I was told to do.
I was looking for a method to do that in the right way.
magic:
I1 is right because the output is centered at zero.
If you want to see more output power, increase V4 amplitude of course.
