An irritating power issue with my Deep Impact just popped up (which figures, since I was just considering selling it). The power intermittently turns off and on when the connection to the power supply is wiggled around. Usually, when I first plug it in, it won't turn on. Then, I'll have to wiggle around the connection to the power supply a bit until it turns on...at that point, it works fine throughout a gig. I think this might be a pretty simple fix. I opened the DI up, but then remembered that I'm electronics illiterate and promptly closed it up again. My best guess is that a solder connection might be a bit loose, and when the power supply is plugged in, it pulls that connection apart a little bit. any other (more educated) ideas?
