In Reply to: RE: My Pleasure! How many junctions did you treat along the AC wiring? posted by Dryginger2 on December 31, 2023 at 18:26:19

I am a little confused.
You use more than twice the amount CDC advised? 0,1 oz = 2,83 gram.
And further, as I understand, the amount on the ground should be about half (0,5g) of the amount on the + side (1,0g), you do the opposite?
This is a powerfull tweak, thank you CDC.

Actually you'll find as I did that you'd have a hard time cramming much more R salt behind a standard wall plate than the originally mentioned 1 gram/.5 gram formula. This unless one wanted to encase the entire plate in R salt. When I experimented, I reduced the amount from that point down to .7 gram/.3 gram on a handful of receptacle and switch plates.

Mojul,
To be candid, I bought CDC's recommended Chinese measuring device from Amazon and found that it never gave me the same answer twice. So I guestimated from its indications that ~0.1g was a thin amount at the end of a bag and an even thinner amount spread along the side of a bag was ~0.05g. Not satisfying to read but buy one of those devices and you may start to understand the problem...
I use bracketing (i.e. going over the top) to discover what's too much and then reduce from there. Having applied Rochelle salts to Ground (@ bottom) and Line (@side)to hear the effect on room outlets, I stripped out the sides to determine the sound contribution from Ground and by deduction Line. I then added the salts to Ground (@bottom) of room light switches.
It was clear to my ears that ~ 0.1g works without deleterious effect on Ground but ~0.05g is the max before sound degradation with Line. I then carefully applied the tweak to waste disposal/ refrigerator/ range outlets. And the result launched the tweak to a completely new level, probably because each has its own circuit and they generate much more EMF. I cannot emphasize sufficiently the disproportionate sound quality improvement from investing the extra time and trouble.
Have ended up by using Rochelle salts near the ground of every single outlet but only adding them to the side of Line with outlets of disposal/ refrigerator/ range and the AC conditioner for my music system.
No way to avoid testing levels for yourself as systems, taste, ears vary - to say nothing of measuring machines. Your time will be well spent as CDC has unquestionably given us the most valuable tweak particularly when applied to every single active circuit whether in use or not.

I found the project to be interesting, educational and inexpensive. If one takes the time to tune while applying the tweak at enough junctions in the home, the performance gains are outstanding. There are a lot of high performing tweaks I employ, but for the money spent this tweak yields the highest performance.
I am glad you are enjoying the benefits of the tweak.
Here's another Line application if you have a conditioner isolating Line as the W-3900 'Hi-End Noise Filter' does with its single circuit to the 'Reset' button. Attaching a small bag of Rochelle salts against the casing nearby significantly boosts musical depth dimension and volume without bloat. Put too much and noise raises its ugly head.
There are several other uses or applications for Rochelle salt to lower noise. You would have to experiment with the amount to use. I would start with "less is better". Inside components by LED lights and by fuses. If placed into a small zip lock baggy just place the bag by different sections within components and listen for changes. Once you find a positive placement, fine tune placement and amount to be used. Obviously going inside components be safe and is at your own risk of shock! I am not responsible for anything you do!
A very small amount of Rochelle salts opposite the transformer of a linear power supply (and nowhere close to its circuit board) has proved beneficial.
Apologies. After applying even tiny amounts of R.salts to three LPS's, it proved SQ degrading.
There is a lot of trial and error or experimenting required. By LED lights work well, fuses, SMPS cable at where the wire exits the unit are a few places to try.
My improvement from applying Rochelle salts to outlets/ light switches/ and Internet proved to be limited and distorted by RFI from four overhead LEDs and two twin sets of fluorescent lights sometimes used nearby while listening. That invoked a 'congestion' ceiling of fatigue limiting listening enjoyment and messed with proportions of line and earth treatment.
Neutralizing that RFI with Rochelle salts has ushered in a new world of open, free sound that changes everything including those line/ ground proportions.
So, if anybody out there has congested/ fatiguing sound, treating the RFI of LED's/ fluorescents with Rochelle salts as CDC advises, is likely the key to the listening prison which just became so much more clearly defined.
Has anyone tried Carbon Fiber? Carbon fiber is known for absorbing EMI. I would Iwould think a faceplate made of CF would also work.
