Name : Uproar
Issue : No out put
Hey Guys, need a little assistance on this. For some reason I'm not getting any out put on this build. I've checked and changed a bunch of things...here's the list.
-changed the blue LED (originally installed wrong way)
-Tested ground continuity all good / no unwanted bridges
-tried new ICs and diodes
-double and triple checked polarity of diodes and electo caps
-double checked wiring in and outs
Voltages of IC1 + IC2
1 = 4.5
2 = 4.5
3 = 4.5
4 = 0
5 = 4.5
6 = 4.5
7 = 4.5
8 = 9

Help if you can. Thanks in advance!
Your voltages look correct. What about seeing if you have output on lug 1 of the pot. It kind of looks like your output wire might be soldiered to the ground pour, but I can not see for sure. I would definitely probe back wards on the schematic and see where the audio drops out.

Hmm I though I checked that. I'll have to give it another look. Thanks for the eyes though, I might have over looked that.
I look something like a brigde not so sure but looks like that, looking at the pcb its a solder bridge, its about r6 and r14,
check that you may be grounding the signal over that brigde
And the winner is....Cody! The tiniest little solder bead was bridging the out put wire. Thanks again guys for the extra eyes!
