Clone of Redesign of forestcaver's Benjolin 1.6, itself a version of Rob Hordijk's Benjolin. Warning: the silkscreen references for C7 and R39 are swapped in the KiCad files and in the published gerbers, which breaks the resonance circuit if you follow the silkscreen. Builders also report the power header drawn upside down and that Q1 wants a BC547 or BC847 pinout rather than a 2N3904. Passives are 1206 and the SSM2164 is a DIP part, so it hand solders more easily than the original.
