Aion obscura issue

So I’ve checked and double checked everything and I can’t figure out why I don’t get an effect sound with this build. Bypass works perfectly though. Any help would be appreciated.

I would reflow all of your solder joints. The solder joint to the ground in the power jack in particular looks like it might be a bit dodgy.

Other than that, I don't see any obvious issues. Your EL caps and transistors are oriented correctly, off-board wiring looks like it's connected correctly. Could be a lot of things, though--since you soldered the transistors directly, maybe one of them got fried if you left the iron on too long; bad trace; short somewhere, etc.

It could also be that you just plugged your cables into the wrong jacks. You would still get bypass but no effect.

If you've eliminated the obvious, then it's time to bust out a continuity or audio probe and trace along the schematic.

Thanks for the reply. I’ll give that a shot.

I don’t see anything obvious that stands out. Everything looks good from the pics.

I’ve done this before!

I have an issue with this build myself. It only works if I'm using a very high mA 9v dc adapter
edit - nvm it was a bad solder joint at the dc jack. that symptom was new to me tho lol

Did you try it with a LED connected to the pads? I can't see how voltage comes through that daughter board on the shematic but just a thought.
