resolved / anybody recently made Aion Electronics Deimos / Nucleus ?

Hi, recently I bought those 2 PCBs but both of them does not goes well. Does anybody successfully made?

I tried audio probe and

Deimos can trace the sound until R4 but sound no change while fuzz knob tweaked. no sound after Q3 bias.

Nucleus can not trace the sound even after Q1's collecter.
There are only tickering noise comes from TC1044.

Post pictures and voltage readings of your builds. It may be something like a wrong resistor value or something like that.

It may be a better idea to create a topic for each board, so it'll be easier to check what may be wrong with one and with the other.

For Deimos, is R7 a low value resistor, a jumper or an empty space..??

Hi thanks for reply.

Finally I found the reason why these were not working.

I did not understand 'power ground' means and did not wire.
Now it's working with great sounds!

Yep, on anything with a charge pump or inverter I will typically wire the power ground separately and only join it to signal ground on the footswitch board. So the wiring diagram shows an extra wire on the right side, but it's easy to miss if you have built several other of the projects without a charge pump.
