Hello to everyone
I am French. But I will see a doctor to treat me

!
I'm part of a forum for DIY
http://www.elektor.fr/ and
Francis Ibre is a great help to me, but I cannot monopolize all of his time for me.
I have read many many page, here, on the GU50 but I can't find what I'm looking for.
I would like to make an amp PP 50-80 W UL. I'm ready to do a report on its implementation, on this forum and that of elektor, to help newbies like me.
I am looking for a diagram that has been proven (the pyramid looks very well!) with references to the Transformers from output to order, the bias setting, some values of voltage to verify my prototype.
If I not understand the curves of the tubes, I know read a schema and realize it.
A brief overview of some achievements (thank again Elektor for his help):
