    Do you have shielded IC's?
    Disconnect all IC's except from one clean source.
    Joe had a problem with his TT transformer, and I made a set of shielded IC's for him. Problem solved.
    Please. Please contact me a ben62670 @ yahoo.com. Make sure to include who you are, and you are from Polk so I don't delete your email. Also I am now physically unable to work on any projects. If you need help let these guys know. There are many people who will help if you let them know where you are.
    Thanks

    Fellas, I have been thru all of this before. What I'm asking is that if I know I have bad juice coming INTO my house, what are my options at this point?

    That's the question.

    Power Saver 1200

    It's a capacitor for power saving not sure if it really saves power, but that is a big AC filter if nothing else.

    No, there has got to be a way to eliminate this. Damn you Early! :D

    I have not come this far to quit. If I know that the rig can have no noise, then it shall be.

    Ground loop....everything is plugged into the power conditioner,plugged into one wall outlet.....ground loop.Had the same problem for a while.Changes cables...helped alittle,but still there.Plugged receiver directly into wall.......helped alittle more.Hooked up amp directly to wall....no change....put cheater plug on amp,direct to wall...bingo,dead silent.Too many grounds going to one place.You have to go at your gear a piece at a time.

    Tom break out the Fu*king AM radio and walk tell us if you get a static on a station any station talk or music. Try it on batteries try it in an AC outlet.

    If your whole building has a problem, and your sure you've eliminated the equipment itself, then I would contact your utility.

    Now, when you contact your utility, you can't just talk to some CS Rep. You need to speak to a distribution engineer. If you have a decent engineer in your area, he'll at the very least understand that you've taken every step you can on your end to get rid of this problem. Tell them you think you have some harmonics and dirty power and that you have sensitive electronics that manifests this problem. If the building (not unit) next you if fed off a different transformer and you still have a problem, those transmission lines, could, theoretically, be part of the problem. Being 3-4 football fields away should be more than enough to eliminate the transmission lines though.

    Since you are in Charlotte, I'm assuming that your power company is Progress? If they are halfway decent they should have recording equipment.

    It sounds to me like you might need a power regenerator. What could be happening is that one of your neighbors has some sort of appliance that is causing harmonic distortion and noise to backfeed into the power lines that supply power to your house, and probably several others as well that are fed from the same transformer. A solid state variable speed motor drive (VFD) is one such device that will do this.

    About the only way to clean that up is with a regenerator. Expensive, but probably one of the few soloutions available to the consumer for this type of problem.

    Is someone growing a lot of weed in one of their units? Many Metal Halide, or fluorescents can induce a large amount of RFI. Just for Ha Ha's wrap your IC's will some aluminum foil.

    I didn't read anywhere in the thread about this, but...
    Is your main loadcenter balanced? May be worth checking into that as well, certainly an
    inexpensive, easy thing to do, IMO. And worth doing even if it doesn't address your current problem.
    So, are you willing to put forth a little effort or are you happy sitting in your skeptical poo pile?

    So it looks like you have 2 possible sources of your dirty power: someone's appliance on the same power loop that's backfeeding into the system, or some part of the transmission system that belongs to the power company is bad.

    In the first case, I guess you could go door-to-door and ask if they have any weird appliances... which would be awkward in a big way. In the second case, bug your power company until they fix it. Now, how you tell which case is actually the culprit is beyond me... Good luck.

    Use only the amp, speakers and a battery powered signal source to see if the noise reduces.

    I don't know if the power conditioner has a line filter or not, but I use one for my audio gear. It basically shunts frequencies other than 60 Hz.

    Do you have any kind of home automation?

    The tripplite LCR2400 is an excellent choice as it adds voltage in brownout conditions as well as cutting back when voltage is too high. It is a standard conditioner and surge as well. My system lost some quality when I removed mine. (sold it before realizing what it was doing for me).

    Ok now I confused on this thread :rolleyes:


    So is this coming from the AC feed to house? Or RF noise?

    Using an AM radio to a station talk or music powered by the Batteries no noise ok plugged in noise. Ok noise is on AC line.

    Using an AM radio to a station talk or music powered by the Batteries Noise then you have RF noise issues.

    We need to know which is the source of the noise to help or do we know for sure. I'm a bit lost on this thread.

    Trailers are usually near airports, power lines, and all the aluminum attracts tornado's, but I think it may be a good RF shield:D(except do to latest post I would have to say its a line issue)

    I was talking with a nuclear physicist that lives on my block and he suggested a notch filter or a lead wall.

    Since you're in the business I'm sure you're familiar with the UL design for this. I believe its the detail known as UL-691. This is a practice using lead sheathed drywall staggered while using lead batton strips to be used at the joints of the boards. To properly meet the design 2 layers are needed with offset joints. A 4'x8'x5/8" sheet of this material weighs approx 400lbs. A shaft wall design has also been used in this design. The could double as an X-ray facility to offset the cost of construction. Let me know if I can be of further ASSistance....LOL

    Lead is overrated. You're not trying to stop X-rays, you have EMI.

    A line filter or notch filter is the place to start if you want to find out whether the noise is coming in from the power lines.

    Again, do you have any kind of home automation?

    So this is RF noise from an outside source?

    Did we determined this somewhere in this thread or we still not sure?

    To me it's like a car which does move so is the engine running or are do we have tires? See two very different problems with very different repairs. ;)
