The schematic on the left . . .
The bottom 6N6P has a 1000uF cathode bypass capacitor.
Remove the 1000uF bypass cap, so that the plate impedance of the bottom 6N6P will increase (so the bottom 6N6P plate does not load the top 6N6P cathode.
English Please.
The Moderator will suggest that, perhaps tomorrow.
I do not know the French language.
I hope you find a good amplifier to build.
Have Fun listening!

I'm in for that project, still in the make, probably only a few years away from finishing it 😉

I will let the experienced users of Headphone amplifiers tell you which amplifier is best.
I have not used headphones for over 40 years.
To me, the important points to pay attention to are:
The impedance of the headphones (the load that the amplifier has to drive without distortion).
The sensitivity of the headphones (most headphones are very sensitive; only a few require lots of power).
The amount of hum from the amplifier (sensitive headphones make you hear even the smallest amount of hum).
The amount of noise from the amplifier (sensitive headphones make you hear even the smallest amount of noise).
And, Most Important . . . Safety:
The safety of the amplifier (what voltage is on the headphone wires, versus earth ground, or any ground you might grab hold of)?

Hello 6A3sIMMER
Thanks for the answer, so remove the 1000µf 16V capacitor, my headset is a 300 ohm impeedence HD800.
I saw another pattern is it better? WCF?
thanks
Regard
