I've read threads on here about how to eliminate ground loop hum, and I traced my problem to my 12 volt trigger connection. My question is, how do I eliminate the ground loop while keeping the 12 volt trigger? Would one of the aftermarket devices such as the Radio Shack do it? The 12volt trigger uses 1/8 inch mini plugs.

It may be possible to cut the shield wire in your 12v line...

Or, one or another piece of equipment needs to have the AC power cord ground removed with a simple 3-prong to 2-prong adaptor.
