In situations where offset trimming to <100uV doesn't improve much if
anything (say, driving an SSM2164), the OP-07 has been handy for use w/o
trimmers.  But apprarently that was a boo boo (woops - better go look at
that module a little harder and see how well it's *really* working).

Any suggestion on op-amps with same offset specs as the OP-07 but
suitable for audio?  Spoze if they get too expensive though it's back to
trimmers....

Thanks mucho,

Buck
