7 x 621-1N5819HW-F schottky diodes SOD 123

2 x 10k 0603 resistors

9 x Thonkiconn jack sockets

7 x on-off-on mini toggle switches https://www.taydaelectronics.com/mini-toggle-switch-spdt-on-off-on.html

Mistake on first run of PCB:

  • do not use 0603 resistors
  • Bridge right hand pad of R1 to left hand pad of R2
  • on the back (where diodes are) connect throughhole 10kOhm resistors from earth on output jacks to either side of final switch
  • connect left hand leg of last switch to bottom leg of right hand out jack
