Ciao Pollix,
some kind of attachments are forbidden on the forum, you'd better zip them and try again.
Pics of the prototype are most welcome

Cheers

Andrea

excused for my answer delayed

This is a link with definitive Project:

http://xoomer.virgilio.it/pollix/my_ampli_g00000f.jpg

...in this ampli, I haven't used current mirror, generator of constant current. The input differential have little load and distortion is less to VAS without cascode (IMHO). The NFB is small ;-) and sound is clear and dinamics.

Bye!
