Hey fam!

Anyone know if the opamp chips are still available for this processor?
I have the dreaded white noise problem and would like to see if a partially open or shorted opamp is the culprit.

Found an old post from Jack Stoner about the opa2134pa. Turns out Mouser still sells them for 9.18 each.

I think I’ll order some up and do up a quick comparison video.

That's good to know. Please post the results. I still have 3 of these units and use them.
