Okay, I took some advice here and there and came up with a design that I think is much more "feasible"... I took a look at esp project 3 http://sound.westhost.com/project03.htm and decided to make my own version with more power output and to be more capable of driving a 4 ohm load. I decided to use complimentary pairs of a1492/c3856 for the OT and BD139/140 for the VAS and drivers, even though I have tip40/41 in my diagram... Does anybody think this is a good idea to make this amp I modified? Please mention if you see something wron in the pic, as in a reversed biased diode,(that sort of thing) Thanks...

P.S. I somehow calculated that this amp sould put out 3000 watts

into a 4 ohm load, which I figure is quite improbable, can I have some pointers for calculating OT power for a class AB please?
