Sounds like I need to stop and get a better understanding of proper grounding. There seems to be some mixed opinions on whether or not to tie earth ground to dc common. I always assumed everything should be grounded to the same ground. Currently my dc components are grounded to the small enclosure I have, as well as the a.c. ground and it hasn't caused any issues, but maybe not the proper way to do it? Just wamt to make sure i have this right before spending time on the new cabinet
