Hi Maxpou,
you could swap the bases of Q14 and Q18 to the corresponding FET drains. increases (ol-) gain and decreases distortion.

Hi Rüdiger,
i use the schematic in post #5 not the schematic in post 7.

Hi Maxpou,
in my opinion
please f*** 2nd, 3rd, 4th harmonics
but beware of this 15kHz peak!
Better use OLG,
true

Hi padamiecki,
i don't understand your all message, but yes i will test OLG with local feedback later.

Thank you! Maxpou

Hi Guys,
what's the best solution for my VAS cascode? use zener or replace it by resistance as show on the schematic. My original schematic is show at post #5. Thank you! Maxpou
