hi, i have a output stage of Sony Str-de495 with burned board and Power supply, so i tooked out its power stage made of 5 pairs MN2488 and MP1620, which are, as you probably know 2SD2488 and 2SB1620s

I have measured all of them, and all seems to be fine

now i wanna build some dual mono or just mono, whatever, and need some schematic because I`m not that expert to do that by myself, on net i can not find anything, so ih you can help me i would be very grateful

here are some pics:

ok, but i need some schematic, i really don`t have idea how to build that thing

I was looking at some "standard" solid state amps and figured out that this darlington can replace driver+power transistor, but not sure which schematic to take "as a sample"

please help someone, thanks

EDIT

ok, i see what you (probably) thought, I found LM4720 datasheet and sow darlingtons in power stage, can I use that Schematic or there are some more developed?
