OK, so I have a PCB from VFX and I'm completely in the dark on some of what the holes are for. I completely understand the resistors and LEDs. I THINK I understand the on/off switch. What I don't get are the +/- 9V in/out slots. I've circled them dark/light blue and dark/light red. Can anyone shed some light on these for me? Also, this isn't the EXACT PCB that I have, but fairly close, close enough to get the general idea.

Did VFX supply instructions? Looks like where the battery (+) and (-) wires hook up...Agree about calling Mr Neubert if there is a question though.

Looking closely at the image, the -9v connects thru the print on the board to the other -9v, the +9v looks to do the same as well, but is not visible behind the switch. Assumingly you can connect the power source to either, and daisy chain it to another item if needed and or have the capacity of power source to do so. :thumbsup:
