Did you ever find a solution? I have the same issue, and can’t seem to figure it out. I’m also building a 49c?

Hey guys, I just finished my build and I’ve got a ground buzz coming through. The microphone works, sounds great and doesn’t have any other noise, just a ground buzz. All of the grounding seems to check out and I have continuity throughout everything. I’ve searched through this thread to see if anyone has had a similar issue, but couldn’t find any posts. Does anyone have any ideas on what I should check? I also ran it through an isolation box to see if that would get rid of the buzz, but it did not. I’m kind of stumped. Also, once I kill the power to the PSU, and the capacitors are still charged, The buzz goes away in the mic sounds fantastic.

Put it in the body and try again.
