I'm not sure about the boards you guys got - but in MINE (there don't seem to be revision numbers) C22 isn't even in the circuit. In the original, C22 hits the same ground trace on the same side as the leg of C23. It seems to be exactly the same kind of error that the other two resistors has - as mentioned in Jed's bugs/errors page.
now - i'm kind of wondering if this has something to do with the 'instability' noticed by some using 22pf cap??
I can't believe nobody's spotted this.... or maybe I just never got the memo?
