Hi Tony

The drawing I made shows hard wires everywhere..but you have to think beyond that..

All the stuff you buy also has capacitance to the chassis, if not some kind of filtering thingy at the PC input, that tries to shunt the bad stuff to ground and away from the transformer..

And, a two wire cord is the worst offender w/r to broadcasting and receiving e/m transients..because the wires aren't necessarily twisted, but parallel.

So, you really don't need 3 wire stuff to be ground loop compromised.

The systems will still be virtual grounded right at that wall outlet, and anything you do on this side of it can most certainly affect the ground reference...Remember your hum problem?? It wasn't stuff coming in the supply, it was your ground being manipulated.. I had a similar prob at home with my powered sub..it popped every time the fan blower turned on..and the sub had a two wire cord. Judicious placement of the power cord and IC solved that problem...(translation, I played with the wires till it stopped, then came up with an explanation based on how it was reacting to changes..)Hee hee...just had ta say that...

That's one thing a power conditioner solution could help with, like JR's, or some commercial equip..most people are unable to work out how the ground is being smacked, and have to opt for solutions that someone has developed.

Cheers, John
