First post, please be gentle

I have been searching the internet for days, looking for a schematic of Dana Halls Lil devil but had no luck. I have read somewhere, that the amp has been discussed on this forum when it was developed. But even after using the search function, I had no luck in finding a schematic.
If anybody that built one of these could chime in and point me to a schematic I would be super greatfull.
Best regards, Florian
