in reponse to your question about connecting chasses - loosen a chassis screw on each item and connect via spade connectors. Earth ground would ideally be a ground rod - but the street side of the water pipe works fine or for that matter the electrical panel ground bus. The idea is to have only one path to ground. Make sure that all your chasses are connected to the ground pin of your ac socket (where your power cord plugs into the item). Cheat the ground pin on all power cords except one. That way you have one path to ground for all items. The only difference in resistance being the short high guage wire connecting the chassis - tighten the screws and this should be in the range of less than 50 milliohms. Just remember, if you later move your equipment around - uncheat the grounds. The only reason this is still safe is that you still have all chasses connected to ground via the interconnecting wires.
Ground Loop
What is a ground loop? I understand that they can be caused by loose connections between components. What else can cause them? What are the effects? I have been told that humming from my power amplifier can be a symptom of a ground loop. True/False? Can ground loops cause damage to equpment?
