Hi - new to the forum so apologies if I'm missing some obvious info here

I built an Aion electronics Helios kit and it doesn't pass signal or turn on even. There is one joint on the board where the pad came up and I think that's almost definitely the issue (I mean its definitely AN issue) but I can't read schematics well enough to know what to jump (I can usually tell by looking at the trace but not this time).

Am I off base with the diagnosis? And how do I tell where it's supposed to go?

(Note: CX1 and C3 aren't meant to have components, in case you're curious why they don't)

Lifted pad is a Ground pad and might interrupt GND continuity to some other "vital" point..
(by itself, it just cancels dual diode pair clipping configuration..)

OK awesome that confirms my suspicions about this particular pad - is there a fix for this? Something to jump etc?

No, the missing pad connected to nothing, don't worry about it.  Something else is causing your lack of sound.

Can you post the DC voltages for each pin of the active components (opamp and JFET)?
