I have my VCR, XBOX, PS2 and Gamecube connected to my receiver through a switchbox. It hums pretty loudly so I got to thinking that maybe I have a ground loop issue. So I want to put together a couple audio isolation transformers inbetween the RCA connectors and see if that solves the problem. The trouble is that the only ones I can find are these from Radio Shack.

They freq response on those kind of sucks. Would it be better if I put two in series? Or where can I find some better ones?
thanks.

So maybe I worded what I'm looking for wrong... When we had these problems in my band, we throw on a DI box and click the ground lift switch.
I could buy a pair of Behringer Ultra-DI boxes with FR from 10Hz-93KHz for $32/ea but I gotta believe that the transformers alone are cheaper than that...

I'm not looking for AC line filters, I'm looking for a 1:1 transformer that I put between the RCAs coming out of my switchbox and the RCAs going into my amplifier...

SY said:You absolutely want to read and understand Bill Whitlock's papers on the Jensen Transformers site. IIRC, there was one in particular on troubleshooting ground loops.
That would be this one: Hum & Buzz in Unbalanced Interconnect Systems
