LA is connected to the anode (+) of the led and LC to the cathode(-) of the led. seems right. My SPDT switch is connected OF to top, CO to middle and LF to bottom of the switch. that seems right too.
do i have to connect the GND next to the OUT to the ground since I'm using banana sockets?

thanks for your speedy reply.here is the pic… of the board and the wiring…yes i was aware of not needing a cable for the 0v part but since it doesn't work, i thought it might be some grounding issues.bestD<IMG20171229191751.jpg>< IMG20171229191607.jpg>On 29 Dec 2017, at 19:05, "Ken Stone otherunicorn@...

You do not need a link between the 0V holes above the 100uF caps - that is a point where you can access 0V in case you need to wire something to it. The link will not hurt anything though.On Fri, Dec 29, 2017 at 7:12 PM, pigeonsmusik pigeonsmusik@...

And I've connect a orange led to the LED driver section and LD driver to the output of the banana jack that i'm using.I'm using MOTM power distribution board from CGS and only +15v, 0v, 0v, -15v is connected.I can't figure out where i went wrong. Any ideas or help would be greatly appreciated!ThanksbestDennis--Ken Stone otherunicorn@...Modular Synth PCBs for sale <http://www.cgs.synth.net/>
