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?

This page has the testing and troubleshooting information, guide, and procedures. Look for the sections “Initial DIY Testing”, and “Troubleshooting Problems”.
Yes, it’s an enormous wall of text, but it’s very procedural and the information will be there.
