Ha, too late now.
What's special about this Pacific custom resistor, any ideas ?.
From Bybees wat weten we ervan wat horen we ervan...Bijzonder of Bye Bye
1. 25 watt 0025 ohm resistor (not for sale Pacific 1711)
Eric.
AVE...
@John curl...
In my grade school I worked with Odra 1305 mainframe. For few weeks only, and I was 8 at that time...
Let's make a little summary:
1. Quantum Purifier is just a resistor in some ceramic shield.
2. It doesn't work at all.
3. It's just a hoax.
Why are you still discussing this?
There are other audiovoodoo hoaxes you should expose...

Who knows. Pacific won't discuss any technical details or sell you any as this is a custom part for a particular customer and not a catalog item.
It's a 25 Watt resistor. If I was to venture a guess I'd say it was the resistance value.

The disassembled "device" with the Pacific resistor is an old one, not representative of current manufacture. Current parts are smaller and have cheap steel leads.
Someone cynical might think that the product changes depending on the availability of cheap surplus parts (i.e., once the Pacific resistors are used up, the surplus markets are tapped for some other cheap small value resistor for the next run). Others might conclude that the old device is obsolete, the new devices are much better, and that anyone with those Pacific resistors risks being laughed at by his friends and taunted by the girls that he's been swimming in cold water.

If you've read the thread, you'll note that I did NOT disassemble them. I didn't buy them (supporting fraud does not comport with my personal sense of morality), they weren't mine to destroy.
Again, if you feel like there's a wonderful mystery there and want to contribute something on-topic (Measurement and Analysis), go lay out your own money and take them apart.

I belive the Pacific resistor may be a beryllium oxide resistor, not that that makes it special in terms of the QP.
Simulation is done a fair bit on high speed circuitry such as DDR2 and 3 ram interfaces, and is very accurate provided as Jacques as stated you get the models and all the information right. It is a pain but out customer insists on it as well as MTBF figures these days.
JC or mrfeedback, why is this component only available on a small number of audiophile add on sites? and not available to the electronics world at large?

So it is a resistor, although perhaps in distributed form. Does it conform to the Poynting conjecture - if so the effect should be measurable as an impedance? Does it generate Johnson noise?
Where is this stored energy which is converted to heat? Magnetic field from the flowing current? AC field from current fluctuations? Does it obey Kirchoff's laws?
Just about everything we touch today has undergone extensive simulation during its design cycle. Usually several times. The computer power that is used would be called "supercomputing" by many standards. Why? The fab time and cost for even the simplest IC chip is huge. A test wafer takes 4 months to go from raw data to packaged chips and costs about $100K. You don't even think about sending out for silicon until all of the simulations are done. Simulation allows even a complex RF chip to come back from fab in usable form. The simulation tools are complex and specific to IC design. The models ade developed and supported by the IC house that you use. In my world we take these chips and design an RF device. Again simulation is heavilly used. We use ADS from Agilent for RF circuit similation. The mechanical design is simulated for form, fit, and function. Even thermal flow is modeled as is the fields around the antenna and the sound pressure from the speaker. Data from each component and the assembly process is used to model the reliability.
Yes, I started out in the slide rule world, but in todays high tech design environments, it's either keep up with the state of the art, or be passed by it. Realize that the cell phone in your pocket has more processing power and technology than yesterdays supercomputer. Why? Because that is where the money is being spent.
For the record, as far as I know, the quantum purifiers work, are made with 'selected' resistors, as well as the actual purifier. SY is incorrect, but I am not in a position to say more, although I have attempted to answer EVERY question that was either not redundant, or might get me into trouble with people bigger than me.
If the viewed trace is vertically displaced, as by the vertical offset adjustment, then an electron velocity change would cause the electron path curvature to change. If there is no vertical deflecting field, either electric or magnetic, I would not expect a change.
The earth field is roughly half gauss, so there is indeed residual mag field, but it is very small.
If there is an electron velocity change within a device, it would be over once the mean free path within the copper wires on either side of the device were exceeded..any change would dissipate as heat, then the electron is again accelerated by gradient. I would not expect any velocity change to make it to the crt.
BTW, it is trivially easy to cause the electrons to go faster within the circuit. Just decrease the cross sectional area of the conductor. This will increase the current density and electron velocity.
Cheers, John
But decreases the current. The First Law will always need to be satisfied.
In conventional physics (the kind that lets us design airplanes, radio telescopes, and drop payloads accurately on distant planets), yes. But peddlers of these devices claim that the velocity increases reduce noise upstream, which as the measurements show, is totally false.
For normal conductors, this is correct. For superconductors, it is slightly different. I can pinch the current within a superconductor with no resistive increase (edit: there will be a local inductive increase of course..) Only when I exceed the current density maximum will I pay a penalty, as the superconductor will quench.
At room temperature, you are correct.
Hopefully, "drop payloads" means contact at several miles per hour within a balloon cocoon...as opposed to hitting mars at velocities exceeding orbital ones..courtesy of a metric vs english snafu..
I claim that if I wanted to, I can fly by flapping my arms.. I just don't want to.
Claims which are absurd require little time..
I like the saying...if you fall out of a skyscraper, flap your arms for all it's worth in an attempt to fly. The worst case of course, is you fail in that attempt......
Cheers, John
Of course, there's the claim of "near superconductive," which is a content-free phrase, but could be used as a "get out of jail free" card.
"Near superconductor" is indeed a valid phrase.
When I am testing a magnet at 4.5 Kelvin, the copper voltage tap wires are sometimes bound to the power leads. Since they are physically tied to the superconductor leads, they are "near superconductors". When the vtap leads are a centimeter or more from the superconductors, they are no longer called "near superconductors", but take on the name "farther away from superconductors.." The classification terminology proceeds through "stones throw from superconductor, through "not even in the same ballpark as superconductors", to "what planet are you on because there ain't no stinkin superconductors anywhere....(this be room temperature devices, btw..)
Cheers, John
(man, that red was way too much...)
