Nice build, Chris! I'd be suspicious of the damage done with your solder bridge the first time around. Likely this stressed things and it just wore down quickly with the heat in the time since then.
One of the steps in my building protocol is to scratch between ALL solder pads with a fine tipped screwdriver to make sure there are no solder bridges. Then, I visually inspect with a bright light and a magnifying glass. Also, check the bottom of your board to make sure you don't have any component legs hitting the metal chassis. That has caused problems for me with previous builds as well, even happened with a speaker crossover that was mounted on top of sound deadening panel - turns out it had a painted tin-foil layer on top...
