Is there a solder bridge on pins 3-4 or 4-5 of one of the SIP op-amps?

On the bottom of the small board, it looks like there may be a solder bridge between the terminals. In the photo, it's ~1/3 of the width of the board from the left side.

FIXED IT!!!! I know you'll love this one. I traced the plug on the main amp board couldn't find anything. now i knew it only went to power and protection leds and the high input. there was only one part in that area that i didnt know if it worked.....the protection led. sure enough that was it it was passing conductance both ways. put a new led in and now it operates normally.
