Hello,

Quick question.   I thought I had some 12k resistors and I don't.   Should I be fine subbing out a 10k for the circled 12k here.   Would rather not run in series if I can get away with the 10k.

Thanks

That will set the overall output gain of the circuit. Going to 10k will reduce output slightly.

From 1.545 to 1.454 or about half a decibel, to be more presice..

Because it's an investing stage, it will actually go from 0.6 to 0.5, or 1.6 dB, no?
