I'm sure I can find my old mouser BoM and send it to you if you'd like
Ah, ok. So nothing really drastic then? I've got pretty much everything ordered from back when I made my original (ordered enough to make both), I followed the high-end configuration from the site/thread BOM except stayed with 1% resistors instead of .1%.
So essentially, you made changes to R3, R4, R5, and R6? I read Tangent's cranky opamp article, and his suggestions seemed to be lower the bandwidth and balance R3/R4 with R2 and the pot.
I'm not really interested so much in part numbers as just some guidelines or rough values. If you'd like, I could even work on taking the old BOM and looking up part numbers and adding to it.
