Hi

Nice first DIY amp I wish my first amp would have been like that using prototype boards

I have one question about your power amp schematics. How is determined the value of the VAS current with an input stage using this current mirror in symetric configuration?

How to say : It quite difficult to purely calculation, for me I need some adjustment for find out the correct idle current which ensure that VAS stage will not be off while maximum input voltage level is come.
