The next best Tweak ???

There have been several postings at AA about a new tweak from the mind of a gent named unclestu that I would like to share with Audiogon members.

I really don’t know why it works or how it works.
This tweak will cost you about $10 bucks but hold on to your hats...

unclestu discovered that the Ground Control (that was designed by Bud Purvine and sold by AudioPrism)design could be improved on.

You will need to make two sets for your speakers.

What unclestu came up with is to take a 6V Lantern Battery, add a 1000uf Electrolytic capacitor across the top springs (+ to + and - to -) connect a wire to the negative side of the battery and then attach the other wire end to the negative post on your speaker.

I have also made a couple that I plug in to my Preamp and Amp. Those were made with RCA’s ground on the wire end and I used 9V batteries utilizing 9V battery clips.

I've got to say, big improvement across the board, Soundstage, bass, mids, treble. But the most dramatic change is in the dynamics.

This is really going to show my naïveté so I hope I'm shown mercy from the membership here but the 1000uf capacitors I found at various e-tailers and retailers have varying voltages. I've seen 1000µF 6.3V caps all the way to 1000uF 50V caps. Does the voltage of the capacitor matter in this tweak? I realize caps are cheap and I should probably just try different caps but I really want to minimize the trial and error. The Radio Shack one is 35V so I may give that a try first but the other caps would have to be ordered and the shipping rates I'm being charged is taking the fun out of this tweak. Thanks

The 1000uf 35V Cap from Radio Shack is what I used.

HI Ozzy,

Can you be more specific on what you did for the pre? Thanks a lot.

Dtsag, I used a 9V battery snap on clip that you can buy at Radio Shack part #270-0325 package of 5 for $2.99.
Solder the 1000uf Electrolytic capacitor to the ends (red to + and black to-).
I then soldered another wire from the black wire to the ground on an RCA. It makes a nice compact unit that you can try on various pieces of equipment. It seems to take a few hours to charge up.
