Hello, I'm here again.
This is the audio amplifier structure:
This is the output of a 1kHz sine wave:
Do not care about it doubled, it's my phone that can't do a decent photo in the exact moment, because the signal generatore pulses and it's not continue.
There is a strange distortion in the low part of the wave. Whats the problem? The double-transistor bias? (I've already corrected the bias resistors). Or the unmatched transistors of all the amplifier?
