Hi everyone, I am trying to design an AB amp for my car. I have put together part of the circuit by trial / error / maths so far but i stumble upon a behaviour that i cant explain. If i probe the emitter of the transistor with an oscilloscope i can see my sine wave but as soon as i plug a speaker between Vout and gnd the signal stops. The op amp is a LM358N and the transistor is a TIP42 (ill add the 41 when i get a satisfying top half of the wave).
What am I not doing properly?
Thank you for your time!
Ps. The circuit is derived from a circuit that i found in "41 projects using 741 IC" and that gives me the same behavious even when complete.
