Looking at your calculations, it would seem that the U5B gain is a bit off. This should be about 4.07 (calculated from 1k1 and 270). The 6k and 3k resistors in your spreadsheet are actually 6k8 and 3k3 according to the schematic (V1.1 and V2.3).

Thanks for that feed-back. I am not familiar with the 6k3 label, I thought it was a multi-part indicator such as 3-ea 6K in one package. I will make those changes and post the new file with an “A” appended to the zip filename.

I searched this topic and discovered that this exponent encoding was adopted for small surface-mounted components. I have been out of the electronics industry for about 8-years, so I guess I just learned something new here.

Thanks, this is exactly why I wanted some review before I released the results in a stand-alone post. Still looking for any additional comments from others.
