This might be a stupid question, but the 3pdt wiring diagram shows 2x9v&gnd on the main circuit board. I’m building Dr Rock and SWAH kits,both of which only have 1 of each. So how do I wire this up? Is there another version of that chart?
There’s never a stupid question mate we all do it differently
The duo of ground and +9v pads on the 3PDT board are there to make it easier for combos etc
What you can do is wire your +9v and grounds straight from the DC jack to the 3PDT board then use the extra one’s to wire power and ground your main pcb
