I just finished my first DIY project. I bought the JDS Labs Cmoy BB v2.03r. the good news is it works well and sounds great. The bad news is I've realized I installed a regulator backwards, position U4. I didn't match up the flat side of the regulator to the picture on the board. so the center leg is in the right spot but the other two are swapped.
I have not yet used a rechargeable battery, nor have I attempted to plug in a power supply, seeing as I don't have one. My question is... are these things directional? And will I damage the CMOY if I attempt to plug it in?
