LC,

Thank You for Yours really generous and patient support, my old eyes and late night brains are hardly correlated . . .
I did the changes and will skip the mission impossible, as You enlighten me the chances are really low. I found on a web a similar Mos OP of Mr. Bora design and is to be a good sounding one, maybe interesting to try that OP stage latter. For my the very first try this would be it, maybe also a conventional OP Stage for comparing the real sound difference between the two and chose the most natural one

Thank You,

Just one, to make-it the way we can cut the printed circuit it in two parts: power supply and amp. Several reason on my point of view: I allways prefer ti share the same power supply for both channels for stereophonic image stability , and i prefer stabilized ones, as i previously mentioned for sonic quality. Last, some people would like to upgrade their existing amp, keeping their actual power supply ?
Just my two cents.

May-be this can reduce a little distortion. (see around output)
