Phase reversal??
What is this board for?? It'ss mounted to the inputs and the pots connect to it also....it's one of the Handley 700B's....
It's a pre-opamp.
Making up for signal loss on long cable runs?? Where's BD when ya need him??
Could have been an instrument amp conversion?

Converts balanced input via phone jack to single ended for industrial applications...
No shit - where's BD? He could shed some light on this with his real world experience.
Derek - have you heard from George recently?
It could be a long ass cable run with a significant drop in voltage but this op amp could easily overdrive the controller board. I would ass-u-me that this circuit was designed to limit the output relative to the amplifier controller board input parameters.
