Hi guys
My yamaha PM180 mixer has a broken Yamaha NE80100 opamp in the output amplifier. Since these opamps are pretty hard and expensive to come by, I want try to use another opamp in there. I have some spare opamps with the same footprint that I would like to use, but they are rated up to +/- 20V and the mixer runs on +/- 22V. So my question is this, what would be the best way to drop the voltage to +/- 18V on only the opamps on the output amp card, or is it better to drop the voltage from 22V to 18V from the psu?
