OK, looks like:
- The switches are reversed, left position actually sends to SWOUT2 instead of SWOUT1
- R14/R15 and associated LEDs are swapped, R14 is for SWOUT1 but is positioned next to the
Gate Out 2jack and vice versa - The
Gate Outjacks are correctly connected
So what ends up happening is left position sends the gate to Gate Out 2 but lights up the LED next to Gate Out 1.
Easiest fix is to cut the traces to the Gate Out jacks and add bodge wires to reverse their connections. One trace is on each side of the jacks PCB, so you do have to un-install it. Fifth header pad from the bottom should connect to Gate Out 2, fourth from the bottom to Gate Out 1.
(The adjacent pad looks worse in the photo than in real life, but I did clean it up later. Also, you can see how I cut away a bit of the PCB in anticipation of adding the mods. You have to do that carefully to avoid severing the trace to the first jack. Where by “carefully” I mean “more carefully than I did”. Hence the third bodge wire.)
