In article , rickpv8945
@aol.com says... I've actually seen a couple people use WD-40 on a sctachy pot. I've never tried it myself for fear of gunking it up but it did make it quiet. I don't know what happened later. Is it as bad as I think it would be?? I'm afraid to try it on anything I own. bob I used it on an entire board once. It was good for about three months and then was worse than ever. I cleaned it out with DeOxit and haven't had a problem since. I don't care what it's made of, WD40 is not good on potentiometers. Not a very good lubricant either, ( the can doesn't say that it is a lubricant, either) but works fine as a grease remover. That's what I was told also. When I look at the web site for the WD-40 Big Blast can: www.wd40.com/Brands/wd40_big_glast.html The can states: "Cleans and Protects Lubricates Drives Out Moisture Prevents Rust Keeps Dirt and Debris from Sticking" I believe that WD stands for water Displacement and for that, it works very well.

"mr c deckard" Phil Allison: ** Currents have direction - voltages have polarity. ok, got that. but what about when the cable runs next to an AC transformer? that's the part that i don't quite get -- i don't see how it could induce current in one conductor in opposite direction with the other. could you explain? ** This is * sooooooo * simple it is painful to have to explain it. Current can only flow in a *closed circuit* or *continuous wire loop* and it can only flow in one direction **AROUND THAT LOOP** at any point in time. In the case of a two conductor cable the loop has been pulled out and made long - nevertheless it is still a loop. A varying magnetic field will induce a current to flow in a CLOSED loop in either the clockwise or anti clockwise direction at any particular instant. NOW - wait for it !! If you view only the middle part of a stretched out loop is SEEMS that TWO currents are flowing in opposite directions when there is only ONE travelling AROUND the loop. More precisely - the magnetic field actually induces a *voltage* in the loop the magnitude of which depends on the size ( the amount of open area) of the loop and the strength of the field. If the loop were broken at some point this voltage can be measured between the ends with a suitable meter. In my example, the mic pre-amp is such a meter, monitoring the induced voltage from moment to moment at the break and amplifying it. ............. Phil |

You just explained it perfectly. Induction causes a voltage.
heh, then i have a physics book for sale. as is, 'cause it's busted. Instead, it's just that the magnetic field makes the electrons want to move in a certain direction. If there is nowhere for them to go, they won't move. If there is, they will, and the amount they move will be related to how much they are impeded along the path they travel (which is just another way of saying Ohm's Law). - Logan so the electrons don't move yet (no impedance), although they're under a force? is this different than an E field? that is, the little picture in my busted physics book says the electrons move to one end of the coil (under an E field). cheers, chris deckard saint louis mo |

Well, OK, they move. There is nothing stopping them from moving down the wire, except when too many of them bunch up at the end and the like charges start to repel too much. They just can't leave the wire[1]. If you consider the transformer as a unit (which is what I was doing), they don't move. If you think about what's going on within the transformer coil, then I guess they do move. - Logan [1] At least, not normally... |

What is Phil? Well, in terms of dirt, Phil is that layer that no one wants
but needs in order to base their higher levels of mental landscaping on. Which means nothing, just as Phil does, but ends up being Phil Dirt. What does Phil know? Well, he seems to have his mouth moving but I'm not so sure that he's not just chewing his cud because it seems that Phil answers questions, over time, who's answers contradict each other, but what do I know? Well, I know I'm not Phil Dirt. How does he express himself? He uses absolutely no reason behind his extremely intelligent posts because he doesn't have intelligent posts. He argues for the sake of arguing yet not actually knows of what he argues. He lambasts those that do know because he doesn't know, yet again showing that he is Phil Dirt. Garbage, buried years in the ground with a small layer of this guy will ultimately burble up with a foul odor, emoting something of which it thinks important, but only to be relagated to the realm of Phil Dirt as is sinks lower into the abyss whilst those who walk over it complain about the smell. -- Roger W.

Again, just Phil Dirt talking. No light oil is worth it's low viscousity in
lubricating moving parts, but it might be pretty good at killing parasites on evergreens. If it just didn't dry up and kill the evergreens in the process. I suggest that ** Conductive plastic pots are have not taken over the market - carbon track ones are by far the most common and the most likely to become noisy. is not a statement in fact, nor even a statement in and of itself. I've never seen the english use of the combination of "are have" before. Now perhaps it's just a typo, but one such as Phil Dirt couldn't possibly post something he hadn't proof read, could he? Oh no, not Phil Dirt. You realize, don't you Phil, that I'm saying you suck dirt into your mouth, **** dirt out your asshole, and inbetween have absolutely no excuse for having an existence except to keep dirt aerated? In fact, it appears that you could walk under a worm with a top hat on and not have to duck. -- Roger W. Norman SirMusic Studio "Phil Allison" wrote in message ...

** The loop formed by the mic, the two wires in the cable cable and the
preamp input is ONE circuit. It makes no difference to the induced VOLTAGE seen by the pre-amp that there is a mic's voice coil connected in series. Go and do the test I suggested with the length of wire - it is important to first *KNOW* how nature behaves and then try to explain it to yourself. Phil, I understand it is one circuit -- but I understand the two wires in the mic cable with impedances on either side to behave as seperate coils. Here's another experiment that I'll try: the 2 wires running next to the AC transformer are symmetrical -- you could simulate this by wiring 3 mics in series, but to maintain symmetry, mics 1 and 3 should be opposite in polarity, right? I'll then set mics 1 and 3 next to an AC transformer. The studio is booked up untill tomorrow or so, so I won't be able to do the experiment until then. Cheers, Chris Deckard Saint Louis, Mo |

Go and do the test I suggested with the length of wire - it is important to first *KNOW* how nature behaves and then try to explain it to yourself. Phil, I understand it is one circuit -- but I understand the two wires in the mic cable with impedances on either side to behave as seperate coils. ** You seem not to "understand" anything. Here's another experiment that I'll try: the 2 wires running next to the AC transformer are symmetrical -- you could simulate this by wiring 3 mics in series, but to maintain symmetry, mics 1 and 3 should be opposite in polarity, right? I'll then set mics 1 and 3 next to an AC transformer. ** The fairies and goblins are coming after you next. ........... Phil |

Phil, I understand it is one circuit -- but I understand the two wires
in the mic cable with impedances on either side to behave as seperate coils. ** You seem not to "understand" anything. well, my wording may have been a bit incorrect. perhaps i should say that this is how i understand it. but i also don't understand why, when you run a 20' cable from a preamp out to a mic, and 10' out it runs by an AC xformer, the two wires wouldn't look like coils to the magnetic field coming from the xformer. what am i missing? Here's another experiment that I'll try: the 2 wires running next to the AC transformer are symmetrical -- you could simulate this by wiring 3 mics in series, but to maintain symmetry, mics 1 and 3 should be opposite in polarity, right? I'll then set mics 1 and 3 next to an AC transformer. ** The fairies and goblins are coming after you next. does this mean you think that the results from that experiment would be useless? this is how i understand the model of a preamp, cable, and a mic. i'm following this thread to understand what is wrong with that understanding, and what the correct one is, which you seem to know, right? i began setting up the experiment up tonight, and i did do a preliminary experiment with my meter. i found that meter, set to read current, detected a current. i found that my meter, set to read voltage, detected a voltage. does this mean that a magnetic field will induce current and voltage? or just voltage? thanks again for your time and patience, phil. i've recently started to dig into the physics behind all this stuff i use every day. cheers, chris deckard saint louis mo |

"hank alrich" wrote in message ... Is there a serious chance that if we ignore this dip**** he'll crawl to some other forum and **** it over with his trudging witlessness? We could give it a try. They've been trying on Aus.Hi-Fi for years. Still no luck. Now he's here too unfortunately. TonyP. |
