My Question relates to this audio amplifier. The 8 ohm resistor is a speaker. As you can see from the photos everything runs as should until the capacitor (C2) is added to protect the speaker. Then everything seems to become ruined. The graphs shows the voltage at the collector of Q1 and the voltage at the emitter of Q2. I do not understand why. I expected the capacitor (C2) just to act like an open circuit.
