  1. Static electricity is one of the first things covered in Electricity 101. For us, the only time it's a concern is when plugging in sensitive circuits or computer cards.
  2. How were you able to find the Leakage Resistance >350M Ohm? That value has not been available on the long threads. the 52 Ohms is of course the Radio Frequency Characteristic Impedance measured at 1 MHz
  3. As above, gasket all edges. limp weight is most important. a layer of thick sheet rock/plaster board on each side, won't cost much
  4. Note that the Robert E. Greene editorial is 1600 words long and that the Robert Harley reply is 1000 words. http://www.theabsolutesound.com/articles/measurements-listening-and-what-matters-in-audio/ It seems that Mr. Harley took off on a tangent (rant) and his reply has little to do with the editorial.
  5. In the schematic. Junction Box >> Customer Unit >> Earth Rod is incorrect and dangerous. * * * * * * * * * No the USA does not use the 'TT' system, but the connection differences to Planet Earth are external to the home's AC mains wiring.
  6. Note to other readers, @ASRMichael has dangerous misunderstandings about how electricity works. * * * * * * * * * a] do not remove or modify any Protective Earth/Safety Ground connections from your components. b] do not replace any Protective Earth/Safety Ground conductor withe a wire that is not part of the circuit's AC mains cable. c] do not run a wire from your components to an external Planet Earth grounding system. d] do not add an external Planet Earth grounding system that is not part of the existing system.
  7. Much of the above Dr. Archambeaurt Power Point is very serious engineering so just skip to slides 30 thru 37.
  8. If he is connecting it directly to a Planet Earth grounding system what he is achieving is very dangerous! Any connection to Planet Earth must flow thru the Safety Ground/Protective Earth back to thew main breaker box and only then can it connect to the single Earthing system.
  9. Remember to low pass filter your square wave.
  10. Any cable worth considering has it's (2)R's, C & L along with a description of it's construction on it's spec sheet.
  11. No Thermistors are used to limit inrush current at turn-on. Once they warm-up their resistance drops to a low value.
  12. NEC and UL now spec 125V as the nominal unloaded line voltage. So don't be surprised if you see an occasional reading in the high one twenty voltage range. This can be a problem for legacy and boutique components that were designed for the 110 to 115V era. Much of what is called the "DC" problem is in fact over-voltage of the power transformer.
  13. Talk about an over-designed linear power supply! It can operate at 50% voltage.
  14. Low line voltage should never, ever damage an electronic unit. The fact that it operated normally for two weeks with 50% line voltage, suggests that it has a SMPS (power supply). A SMPS doesn't much care what the line voltage is.
  15. The above Russ Andrews paper is a mix of good stuff, stuff that needs a lot of editing (of errors) and totally wrong stuff.
