situation: using 5v from case power supply without 7805 now I can hear sound but don't know well about tunning.
you are correct. This was an issue with the first batch of pcbs which I thought I fixed years ago but turns out I never really uploaded the files (shame on me). Sorry you had to go through the build process with a broken pcb and thanks for reminding, I uploaded new files that should reflect the correct orientation.
please check mcp6002 pin4(Vss), pin8(Vdd) connection. pin4(Vss) is connected 5v and pin8(Vdd) is connected GND in PCB. is this right? let me know..
