This is more of question. But Ive heard using info from a square wave can tell many flaws in an amplifier , I so I tried it it out and lo and behold!
Here is the input signal
Now here is output signal
Hmm lets take a closer look...
From what I heard this is "Severe Low Frequency Attenuation" this should be not be rolling off like this, now the question is? How can one overcome this problem? here is the schematic. This is from Bob Cordells Burning Amp 2016 slide using a diff pair with current mirrors, I'm curious on how one should fix this problem?
