Notes means ~$16-20 in parts, depending mainly on whether 8+6 pins + hardware fits on shaek board or similar size perf. MiniADSR derived from the bottom and the following procedure for assembly. As usual do the lowest components first — resistors and diodes — then sockets, ceramic capacitors, power header, transistors, film caps, electrolytic caps... Something like that.
