Echoplex EP3 PCB Traces

[Portersage]

Hey all, I’m trying to rehab a very late model echoplex ep3 (serial 34xxx) currently with severely damaged traces on the boards. Do any of you have any pictures of the undersides of any EP3 boards? There isn’t a schematic for this circuit variation that I can find, and I just want to cross reference with what one should (basically) look like.
thanks for any help!

Hi, I found this in my photos, not sure if it helps! It's from an EP3, I only have photos from the top for the other boards.
