Default WILS-CFP PROJECT

hello
this amplifier has the first stage with a total feedback to allow the latter to operate without
NEVER BUILD
driving voltage of the stadium in VAS
takes place with a perfectly homogeneous mode on both branches
because the gain of the input stage is forced to G = 1
This involves the accuracy of the details
and absence of saturation even in the presence of a large number of harmonics ( piano - organ - full orchestral )
without the need for global feedback
recently my thesis project was the indispensability of a direct negative feedback (made with 2 resistors + an inverting stage )
with "weight" that is very low 2/3dB (fixed gain ratio 1:100 - 40dB to 26dB of amplifier open-loop )
with excellent results that is a very wide soundstage and " airy "
*but just now I started this new battle wilson - cfp
I suspect to be higher (at the moment it's just a project that has yet to be designed with the simulator )
I added the Bias control
and modified the power of final
that remain of the family "true complementary "
ie with the parameter hFE very similar selections without
