Sheilded/Unsheilded Power Cords

Bob's not going to like this,

I wonder how one could do a DIY active shield? Put a dummy load on a small DC transformer and shoot the current up the shield, or wrap the wire around the cable?

I must say that with my limited, yes very limited tester, the shield and drain on the wire I used seems to work very well.

Thanks all,

Marty

I might be over taking too simple of an approach here, but I took one of the little pen things that detect current/voltage(hot leads) and went around my system with the supplied(careful wording here...) and it went nuts.

With my DIY adventure, the pen no longer goes off, as much. It is pretty hard to shield a tv....:)

I think I was thinking of a more "global" approach, basically reducing the junk jumping into the RCA ic's.

I am not wanting to start a gripe thread... But I have no choice but to use single ended ic's on some equipment. Simaudio Stellar to the Simaudio Attraction can only be hooked up in one of two ways... Digital coax or RCA's. No balanced inputs on the Attraction.

The field an unshielded pc give off seems to be large, at least 12 inches.

Thanks all

Honestly, when I was done braiding the wire and all the mess, the DIY were going to be better...No matter what :).

I had not a/b the cables, until just before this reply. "more noise" between the two- nope. Seems to be the same. I had meant this for another post, how much noise is too much? The old crank the volume and stick your ear up to the tweeter, I do here a little noise. Not heard from the listing position, but can hear with my ear on the tweeter. Not sure really how to put this into words. The tuner will bleed into the next/nearest analog input. $6000 bucks for bleeding inputs, huh.

On the flip side the "dynamics" seemed improved with the shielded DIY's. The highs seem higher and the lows seem fuller. Interesting...

The amp circuit to the wall is unshielded, all runs in the room are shielded. The source circuit is actually shielded all the way to the breaker panel. I use balanced ic where possible, from the processor to the amp. With HT, one seems to have a few more devices, which seem to add more possible problems.

No, the existing ROMEX are not shielded. That's the reason a normal person would buy the live lead finder pen(I gotta find out this thing is really called), to find these lines. My equipment is also not placed directly up against a wall, next to these lines.

Please explain what "unwanted capacitance" means. Is this the ability of the wire to store a charge.

Also the power conditioners in the system are a ps ultimate outlet ran into a Richard Gray 400. Really weird part with out the power conditioners, the buzz is 75% louder, plain as day. What I would call very bad. With the ps, same. With the "noisy" RGPS, very quiet. Funny, exactly the opposite of what I would have thought.

I hope I am not describing a long winded minor ground loop hum. This was not the purpose of the thread. This background noise is very minor.

Learning something new every day,

Thanks all
