Do you know which IC number that is? I can easily go look since the boards are out of the amp right now.
Or if you just want to send both I'll take them and figure it out.
Please email to darkartsamplification@yahoo.com if you have them.
I have one that is seriously blown up with many burnt parts on the pre-amp board that I need to get correct values for.
Not sure how this guy blew this up so completely but I'm suspecting he took the output from a rackmount power amp and fed it into one of the in/out jacks on the back. Ground plane traces burnt off the boards and everything.
