I wonder about the caps used in the Pythagoras PCB. I see the 15pF which I assume is one of those tiny Ceramic round caps. I see the 1uF calls for the coated MLCC types, but what about the 407pF and 220pF caps. The spots on the PCB are much bigger than the one for the 15pF, Are these values a film cap? Maybe .47nF and .22nF? I can't see such small ceramics in the bigger spots when the 15pF is in such a small space.
