Thanks Joe! Have tried swapping opamps and noticed immediately that 99V on second channel have been slightly loose and out from its golden socket legs.
It is likely due to transport of the equipment rack every single night for two weeks for those brass band sessions.
I'm afraid to squeeze these golden sockets to get better grip, maybe its better if I try to tighten it up over "belly" a bit with sort of a belt or something.
Tested for more than hour recording and not a single glitch. Thanks again for the tip! Cheers!
Cool great to hear it was a easy fix. Yes it is a good idea to use a cable tie around each opamp and the PCB to make sure the opamp doesn't come out during transport.
