GROUNDS RELATIONSHIPS ON PCB:
- GNDA merges with SIG_GND near pin 16 of U23.
- SIG_GND merges with GND-TRI near pin 14 of U20.
- WOOFGND merges with PSGND near pin 3 of W3.
- PSGND merges with SIG_GND at C60.
- SIGNAL1 on PCB 1/3 (at pin 4 of W8) is the same node as 'GNDA'
on PCB 2/3 (at pin 4 of W1). They are connected via the ribbon
joining W1 to W8.
- RIBBON_GND is connected to GNDA via L12 on PCB 2/3.
- RIBBON_GND is connected to PCB 1/3 via pin 6 of W1-W8.
- RIBBON_GND becomes GNDA at PCB 1/3.
