SOLVED Duocast not passing audio

innerlight

Active member
Hello all!
I am once again asking for some guidance on an almost functional build (pics attached). This one came together cleanly and I was really confident it’d just work 😭.
I’ve reflowed all solder points and double checked components. I assume the dot on the OC71 is meant to match with the square on the Pcb?
Anyway, LEDs light up, pots make sounds but no signal passes in low or high modes when engaged. Signal passes when not engaged. Curiously, when I switch between 9 and 27v modes I get a pop and a split second of signal.
Do I audio probe next? Please guide me oh community.

I’m not sure how you ended up there, I had asked you to try a jumper to a suspected trace that seemed it could be bad based upon you saying to c11 it was fine and r14 it was bad
Sorry I think I articulated poorly above that I tried c11 and R14 again and they seemed ok, I was getting audio off both.
 
Any report welcomed.
OK!
Tested all of these points for continuity. All were good except the silver/grey points (middle point of boost foot switch to output pad on PCB.) I ran a wire between and voila! Must have damaged that trace somehow.

I’ve attached pics of the final product!
It sounds great on synth and keyboards and bass. I don’t love it out front of a JC120, but it’s probably better into a tube amp.

I want to thank all of you deeply and sincerely. I’m learning so much and I can’t believe how generous you all are with your knowledge. Hopefully I get to a place I can start contributing too!
In the mean time I thank you profusely.
