Behringer Xenyx 802, looking for schematic

Sometimes companies are shy about providing service data to un-authorized requests...
Perhaps the fear of being "copied" is part of it, but I ought to stop there in my comments about "copied" engineering and "certain" companies...

I'll see what they say, but I have my doubts.

Gotta love the Research and Duplicate department LOL.
