So
IC 43 pins 10, 13 & 14 all need connecting to the adjacent rail
IC 39 pin 14 needs connecting to the adjacent rail
IC 23 pin 10 needs connecting to the adjacent rail
Hugo, I notice in the image you sent me, that IC23 pin 10 is not connected ?
I have updated the Kicad PCB files but not yet produced Gerbers as its some time since I did it and can't remember the steps.
Gary, I was looking at your updated Kicad file and I see the fixes for Board 2. But on Board 1, IC23 - Pin 10 is still unconnected. Not sure if we are correcting this "original sin" or not ... ?
