there are lots of other vendors for ooax or catv isolation transformers. Google the term and you will get lots, from <$10 to $100 (Mondial Magic). Or you can mount two of the 75-300 ohm transformers that come with DVD players and insert into the Coax line and see if that helps. If it does, then go for one of the purpose built units.
Ground Loop Hum - Partially Identified - Solution?
I recently added a new power amp (conrad johnson) to power certain speakers (fronts and zone 2). I run through a B&K AVR 507 for my HT processing and 2 channel.
I immediately noticed a ground loop hum upon installing the amp. I was able to rid myself of the ground loop hum by testing the old cheater plug route. Hum immediately disappeared.
Don't want to keep the cheater plug approach as it is just a band aid and not very safe. Is it safe to run a simple ground wire from my amp chasis to the processor chasis? This won't cause anything to blow up (you know what I mean), will it? The ground loop does not appear to be coming from any interconnects (tested by swapping out the ic's to check for this). While I know they carry/continue the loop, they themselves are not responsible for it.
Not sure how the Jensen piece works, any experience (I know a lot of people have this problem from time to time) would be greatly appreciated.
