SOLVED Obsidius Preamp no anything

[FamousAmos]

Howdy,

Just finished an Obsidius preamp which I though I was being pretty careful with building, however upon trying to power on the completed build the first time I get nothing. Already cleaned with IPA and reflowed solder but still nothing.

Any common issues with these guys you folks are aware of that I'm overlooking?

I'm new I don't know what to do

Thanks

Power jack was my guess after reading the LED wasn't lighting. Congrats on the quick fix!

Just want to mention that "Lumberg" jacks are often faked. The ones from Amazon are often garbage. I threw away a pack of 10 after an unusually high failure rate. The ones from LMS have proven high quality.

LMS is who they were from (actually where I get 99% of my off board stuff).

But yes hooray for sure for just a bad jack. I've been very lucky I guess thus far to only have problems with jacks and ic's in my 10 or so builds I've completed.
