06-11-2024: A new revision of the Andes 8HP is made and this seems to have resolved the issues!

25-01-2025: We discovered that the output has a bit of DC offset and that the knob range isn't utilized in full. Luckily, it's quite easy to improve this. It only require 2 resistors to be replaced with a different value. See the image.

02-02-2025: Changed schematic to reflect this. Also sync 12HP version with changes from 8HP version.
