Bad grounding would come out of the speakers. If the sound is coming directly from the transformers, it is vibration, not grounding. Some old transformers hum some don't. It is fairly common with the old Dynaco transformers. In the 80's when I was running a pair of Mark IV's, I heard of people putting wood spacers between the transformer and the chassis to damp the vibration. There are probably more sophisticated ways to damp them. Me, I just let the transformers hum along with the music. I figured sooner or later, they would learn the words.
