build this or not ??

Japanese

Do you know what language all that is in ??? I would like to take a look at that site, some interesting stuff there.

It is japanese. If you browse using GOOGLE CHROME, you will have on-line quick translation for the whole site.

Mooly the only benefit I can find that is of value in having non symmetrical stages is the ease that one can have a desireable THD spectrum. This is difficult but not impossible to realise with symmetrical circuits.

Then again one has to question this desireable THD spectrum, as for example the cyrus amps, especially 3 and up, these are fully symmetrical and display non desireable spectrum but if you audition them they sound mighty good.

Thanks smart, Ill try using google translate in Japanese, Im interested because theres some spice models on the pages and some modifications made to them after the author physically measured real parts.

Sorry... bit off topic I know,
I'm fascinated by some of these... such as the above and the obsession with visual symmetry in circuit design.

its not only an obsession ...its an ediction ...and probably a few more other things especially for people that like symmetry ...

the point is that infections like that do you a lot of harm when you play the pcb game ...cause you like it the same symmetric then a with nice arrangements while "preserving " other design ruls and norms like star ground or feedback traces 😀😀😀

I think you are correct Sakis... and we have said nothing about laying it out in the case symmetrically either... oh dear 🙂

re

boys...😀😀 build this..sound good but not is special.
in the output put other 2sc transistors.
R9 adjust the bias (the value is more low)
Too no much power.
