Ah, thank you for the boot to the head!  I think I got so excited by
this part's bi-polar supply capability my brain started seeing what it
wanted to (could of sworn the data sheet said +/- 18V_max rails... {it
didn't}).  Interesting that this part *appeared* to be running fine at
+/-12V - got full signal swing to the rails and everything.  But I'm
sure the new part is much happier now at +/- 7.3VDC (though it doesn't
perform any better).
 
Thanks for the suggestions!
