We're already behind on Mattnog 2019, but it's not too late! Nate and Stretch and Shelly and others should get off the stick and get on with the nog! I'm concocting a batch today or tomorrow. Time to break a few eggs!

One amplifier has now “new” op amps OPA197. The other has new OP27, one channel with 10K instead of 25K at -input pin.
