Jea48, I'm not a technician nor an electrician. As a result, I'm not in a position to discuss the validity of the steps provided.
I simply posted a checklist provided to me by a technician from an audio manufacturer. It has been very helpful to me in my troubleshooting a buzz in my system.
There are further steps from the tech, which were also helpful, but I think I'll not post them since I'm not qualified to discuss why they may or may not work.
Good luck to you, OP! Buzz/hum is a PITA to diagnose and eliminate, IMO.
