Triwatt Input Jacks. Looking at the Build Diagram. Looks like Ground connects to lug 4 on normal input. Then to lug 3 and 4 on the bright input. Then to 3 and 4 on the linked input. Is that correct? Looking at pictures and instructions cant tell if Ground should only be connected to lugs 4 on all input jacks.

Lug 4 is the switch for the sleeve. The ground wire must be connected to lug 4 on all jacks. With the way the Triwatt inputs are wired, running the ground wire through lug 3 is optional, but can be done just to make the wire routing easier...i.e. running a single wire straight through all four lugs when the jacks are stacked.

If you look at the Triwatt schematic, you will see "lug 3" is not even shown.

The sleeve switch is located at lug 4. For all jacks, the ground wire needs to be attached to lug 4. Running the ground wire through lug 3 is optional with the way the Triwatt inputs are wired, although it can be done solely to simplify the wire routing, i.e. when the jacks are stacked, passing a single cable directly through each of the four lugs.
