Do you have another op-amp you can swap in to rule out a bad op-amp?
Alright, I finally got swapping a BA512 op amp from one of my working Copper Pres. It worked! Perhaps it got fried when the capacitors C505-506 blew? Anyway, that is definitely the issue, I tested the input output knobs and Pad switch. The preamp worked perfectly with the new Op Amp. I am to assume the easiest solution is to order a new one from hairball? They are so small I imagine it would be difficult, if not impossible, to troubleshoot? Glad its figured out! As always, thanks for the help.
