In the KiCad files are 2 more caps (C16,C17 100n) between +5 and GND, -5 and GND.
Yes, these 2 caps were place for super-filtering in the power supply but after tests I did not find any difference between placing them or not. The power lines are clean. So the footprints are in the PCB (
bottom left) but they are not included in the BOM.
The values of C2, C5, C8, C9 and C12 are 47p, the screenshot and the BOM lists these as 270p.
The right value is
270pF, thanks for spotting that. I have updated the KiCad native files. I did several tests for filtering harsh high-freqs, I started using 47pF that is why that value was there. 270pF is a nice value, however there is not a big audible difference if you place 47pF.
