Re: What to do about my humming amp?
the opamps are 4558 types. i did actually check all the voltages at these, and they all checked out ok- i think they were +/-15V, i didn't check the ac, though.  
thanks for your input. i have to wait till the weekend to try out these suggestions, so forgive me if i haven't got anything new to say right now.
