Feedback wanted on dedicated line tweak, please

Posted by Dyak (A) on March 5, 2007 at 11:25:43

Hi Everyone,

I live w/in 1500-meters of about 15-radio/TV transmitters...so I have an RFI issue. See below for the other means I've used to address this issue, but am always looking for MORE / BETTER!

Just wondering if there might be any benefit (or detriment) to taking a run of cryoed Romex and stripping the outer covering off (so that there are 2-insulated conductors and 1-uninsulated ground wire) and then twisting the conductors together (twisted pair). I was then considering taking either foam pipe insulation or an air-hose and use it to cover the pair. I'll buy a 10-gauge insulated ground wire and wrap it around the pipe insulation in the opposite direction that the conductors were twisted. I'm considering usin this to run from my breaker box to my dedicated outlet in my listening room.

Essentially this is a modified form of what Chris VenHaus uses for his flavor 2 power cord recipe. Chris comments on his DIY recipe page, "there is > 1/8" spacing between the safety ground and inner conductors by using the heavy walled high-pressure air hose as a spacer. Combined with the shield removal and the counter-spiralled ground, I believe this design may achieve the absolute lowest capacitive coupling between the inner conductors and safety ground."

The other thought that came to mind was, hhmmmm, if this works w/twisted pair, why not star-quad (i.e. modified Flavor 4 recipe)?

I understand that the insurance comany may not like my idea, though if I do embark upon this mission I will be very careful during assembly and installation.

Thanks in advance for the feedback!

Regards,

Doug

Here's what I got goin' on already w/in the electrical system:

-Dedicated 20-Amp line.
-Furutech FP-15cu outlets
-Modified Monster HTS3500 mkII (added Furutech IEC, VH-Audio Flavor 4, reinforced all traces on all boards, bypassed filtration for amps, and use all Furutech FP-15cu outlets..)
-All cords are VH-Audio Flavor PCs, all use Furutech cu terminations
-Z-Sleeve Extra Heavies on every power cord (waaay good!!)
-A couple of HighWire PowerWraps
-DIY Cable lifters
-Walker SST on all connection points (plugs & IECs, wire-IEC/plug junctions, etc...)
-DIY Jon Rish SQ&D (super quick & dirty) isolation transformer for CDP
-Multiple sized ferrite cores/chokes on power cords all over the house....fridge, fans, computer, etc...but not used in the audio system
-A couple of Quantum ElectroClears
-Some DIY BC86 parallel filters (following some of Al Sekela's suggestions)scattered about the house.
-2 DIY Richard Gray Power Conditioner (Hammond 193L)
