I had read this nice article:

It looks like replacing the two 10R resistors at the source of the input follower will enable you to reduce distorstion by 80%?
Is this usable for a DIYer without a distorsion analyser? I guess the sweetspot will not be the same point as minimum DC-offset?'
But you might have a option to try to listen to different settings of the pot....
Will 20R trimmer be a good starting point or perhaps 100R?

No, but you can trim the distortion a bit by replacing the
two resistors with a 20 ohm (or so) trim pot.

Ok, I should try...
The same might apply to the F4 output stage? The zero off-set level might not be the most optimal setting regarding distorsion?
I have build the F4 with single 50V supply, so could it be possible to tweek on the output also?
This might be 0.47 to 0.1 Ohm source resistors?
