Found the issue with mine and it wasn't the opamp. The ratio switch was dead. The usual symptoms, no compression when engaged, leds go crazy... i fixed the existing one. It took some teethpulling in order to remove it from the board, but i made it. One of the internal sliders that make contact got broken off the rotating wheel. In case one needs to recalibrate the unit, it can be done the same way mnats 1176 or Gyraf 1176 are calibrated. You need external VU meter as the built in works in GR mode only. Audio interface or DAW software can be used for this.
