IGBT Power Amp  

This is one of the best  Project I've ever made. It comes from an old Application note of the Analog Device.
I decided (like most of us) to build it  looking at the specs:

  What stroke me most was the slew rate, very intresting... 

WARNING THE SCHEME ARE BIG!!! SO PREPARE TO WAIT.

I've build it and it's still my favourite (solid state) a lot of impact, extension and clearness, but "no air" around the speakers. I've changed the driver transistors because the MPSU 10 /60 were hard to find. I've used BTJ  TIP's series.  On the main schema there are also some voltages measured in different version of the project. The version I've built differs mainly for the idle current:  (I want  the IJBT  to stay in "A" class as much as possible).
