I bought this little beauty 3 months ago as a quick replacement for a more expensive system, its an STA540 with a pre-amp of NE5532 (though I have replaced with OPA2134s).

I haven't actually replaced it yet as I really love the little thing, and unconventional methodology and simplicity, but some improvements could be made, I'd love to add the power supply to the board and re-distribute the PCB so that it'll fit into a case I have here, make it "all in one".
Now for the plea:
Searching the depths of the internet I cant seem to find its schematic, & my dyslexia is really hampering my ability to convert the PCB into a Schematic i can use, I just cant seem to get it right in simulation. I'm fairly certain it's only a double sided PCB. So I have come here, to you fine folks for a hand in deciphering it.
I have sourced the top and bottom images of the PCB and also a few other bits(a system I believe is very similar to it).
Something that will take me 6hours may only take you 15min which is why I'm asking for a little help
will
