AC or dc? 500uv input? A general type of amp has usualy mv of offset voltage. then there is current offset to contend with since the f/b is large in resistance. unless you made a mistake on input valiue you need a gain of 20,000.00 try lmc60xx family of amps from national semi. AND adding more amps does not make sense one should sufice 130 db is a lot of A.
