SOLVED Aion isotope

[Devolution]

Hi! Can anyone see where I’ve gone wrong here? I’m getting signal through while bypassed and while pedal is engaged but the led is not lighting up and the only pot that has any affect is the master vol. I get the same results with or without dc power connected. I’m also confused by the empty eyelets next to the transistors. I’ve highlighted them on the diagram of the board for reference.

The extra pads next to the transistors are to account for different devices having different pinouts. Are you using 2N5210 or something different?

what does the underside of your board look like?

Can you confirm the correct orientation of the led?

Ok, thanks. I’m using 2n5210’s. Everything on the board was ordered from Aion’s mouser parts list.

There’s not much to see on the underside of the board with the pots in the way. I’ve tried flipping the led around and got the same result. I’ve checked that it’s working with a 9v battery and at the moment the positive side is n the square pad.

I’ve omitted the battery snap but otherwise followed this wiring diagram.

The foot switch daughterboard is upside down.

Eagle eye! Thanks, I’ll flip that around.

All good now. The daughter board was the culprit, thanks benny_profane! Thanks to all that responded too!
