Hello, new BHC builder here. Never done anything like this before and am having fun. So, after "passing" the Resistance and Voltage Checks - I am not getting any sound. I'm sure I've done something wrong, so looking for help. Thanks!

The headphone jack needs to be correctly installed and wired correctly, then you'll likely get sound out of your amp.

What was the issue with the headphone jack connection? Is it that the wires are connected on the wrong side of the jack? I'm only asking in case I have a similar issue.

The headphone jack in this build was installed 90 degrees off from what's specified in the manual and the wiring is connected backwards.
