Al,
Most amps I know use "star ground" or some variation of it for grounding various common points. In short, these various common points are wired together first and only goes to the chassis at one point. A good article can be found from:

Click "Tech Info", then "Advanced (Aiken)", scroll down a little, and you can see "Star ground".
Adding Jensen transformers in the signal path may get rid of the ground loops. But I hesitate adding more components in the signal path.
So for chassis to act like a shield, do you have to wire the chassis to the signal ground or AC ground?
