As I connect 2.2u to S of J5, the output is very lowdivide Rd2 (30KOhm) in 2 x 15KOhm and connect their midpoint to J5's source with 2.2uF or so. You obtain a bootstrap for the second stage which is supposed to lower the already outstanding THD.

I went through the thread with interest.
wwwtttwww I like the possibility of connecting BF and LSK transistors on your PCB. You wrote about using BF, have you tried LSK? I would be very interested in the sound signature when using these two transistor variants. What I don't like about this PCB is that there is too little space for the output decoupling capacitor. I would like to use types that bring very good sound and here it is not possible to use even quite decent models that allow you to fit the PCB from marigno.
