DROP 02 - HeadPhone Amp - Help needed please

Greetings,
My DROP 02 Headphone Amp has no sound output. The red power light goes on. I inspected the board to see if any of the wires were loose, or any signs of caps burning etc. Everything looks fine. ( 2 photos attached).

I do not have the knowledge to test any f the components without help from someone. I really appreciate anyones input and help.

Much thanks,
Mike S

Who did the mods?

EDIT: Ok, I see this was a wallwart-only version of O2 sold on Drop.


Have you tried multiple sources? Different headphones? You’re getting nothing at all, regardless of gain switch position or volume position?
