Why dont you use a non-inverting configuration... as shown on the datasheet.

Also you'll need bypass caps in parallel with C1 and C2 100n should do fine.

I haven't looked at inverting schematics yet but shouldn't the feedback resistor be approx 20k instead of 200k and then R1 could be 1K.

You'll keep the 20:1 ratio.

I'll try to add a picture of you're schematic.

as i wrote i'm not a profi... i found that schematic on platenspeler's site
http://www.platenspeler.com/diy/amps...inclown_1.html
but i've seen nuuks inverted gainclone on his site and the feedback resistor has too a large value...
i choosed the clown because of 6 (7 with the input cap) parts..

If you would convert the Eagle files to PDF you might get more comments. I can't look at them since I don't have Eagle.
