I've fixed ground loop hums by connecting mains safety grounds via contra parallel diodes ie a pair of say 1N5400s in parallel one arrow up the other down in series with the ground connection. They will blow any fuse in a fault condition but effectively isolate things so far as hum is concerned. I use this technique in my ham radio installation and it does cut PSU hum gremlins etc. This might not meet wiring codes etc but it does work.
