caps at the AC outlet to reduce RF?

Has anyone heard or tried this tweak? Putting a cap (don't know the value or the type) in parallel across the hot/neutral leads inside the box of the AC outlet to reduce RF?

That's what the smaller ****** isolation transformers do--and that's one of the reasons they're sooo musical.

GOTO www.magnan.com and check it out! Also, www.thetweakshop.com/

There are a lot of threads on this over at AA. Unfortunately, there are about 30 different descriptions on how to do it, and they sometimes contradict each other on the proper manner, which could end up deep fat frying you.

At Magnan, you need to check out tweaks for your system.

I have put a couple of caps on the output side of my home made isolation transformer (a Topaz ultra isolation model), and I think they helped. I was going to put a couple more on the input side, and maybe add some more in other places.

To be "legal", I would use either X or Y rated caps. I found out about this at AA. They are made to fail open, so you can put them on your AC line, and still be to code. If you just get a high voltage rated cap, and put in on your AC, and it starts a fire, I think you would be SOL

.

I bought my x rated caps from Mouser, 1 uf and .022uf I put them in parallel, then across the hot and neutral lines to ground. They are rated for 250V, made by Vishay/Roederstein.

Not a huge improvement, but well worth the less then $10 the caps cost me.
