Default Non-inverted Gainclone

Does anyone have schematics for a good quality non-inverted Gainclone for the LM3875? I've got the "typical application" from the data sheet, but I was hoping there was improvements made. I have Thorsten Loesch's version of the inverted clone, so I want to build both for a comparison.

Of course I'm a total newbie, so go kind of slow with the technical jargon I can read schematics, and can figure out the p2p wireing, I just don't have a clue about theory or design.

Thanks!

Look at this page: http://home.ca.inter.net/~cfraser/Gainclonehome.htm
there is the non-inverted Thorsten's dessign.
Original GainCard probably doesn't use
C1 (22uF) and use C7 (electrolitic, unknown value)
