I think that in a simple X design with only a diff pair like the JH ones , the aleph (S) cs plays an important rule .
I need feedback on this .🙂

I can see clearly now...

Stefano & Henrik,
TX very much indeed, studying those old threads helped me.
Until now I always used that 47R-300R (multiples) all the
time, I thought them to be necessary!
BTW they help control open loop gain, as I normally dont like
negative feedback, as it is a subtractive process, I tried to
keep olg as lo as possible.

I look at it this way:
It is not the NFB it self that is essential, the NFB by accident is the initial part of the pathway for the X-communication.
X itsef is not feedback, but it travels through the NFB, so the term X-feedback is not that precise.
You need to live with NFB to obtain X.
