Connect pulse generator from older post to your audio amplifier. Set volume to something in the middle. Connect oscilloscope to the output of the amp with dummy load.
You will not see ideal square signal in the output, but all these distortions can describe your audio amplifier.
As there are lots of images in this post and big table. So press on the link to read more about audio amp tuning…
To see osciloscope image move your mouse pointer over table cell.
