Duster_x-2 caps on neutral and ground - dmzwizard 05:24:02 08/31/11 (5)
According to what I read on the Wima spec sheet about their snubber caps, they say they can be installed on the neutral to ground terminals. Have you or someone else tried this in lieu of, or in addition to, the hot/neutral configuration? If so, what were the results?

  That would be a Class Y capacitor, not a Class X capacitor. I've not used nor have seen the use of Class Y capacitors for audiophile applications in my own experience, so others folks might be of help here.

  Anyone tried RFI Supression Caps in addition to the Snubbers, series or parallel to the snubber caps, hot to neutral? A little reading can be a dangerous thing, as it gets the mind a wondering.

    If you have a two wire power cord, place one cap across the hot and neutral. If you have a three wire power cord, use three caps, one across the hot and neutral, one across the neutral and ground and one across the hot and ground. The ARRL (American Radio Relay League) has a good reference book on RFI, How To Treat And Cure It.

      That PDF file I linked you to is a bit long, but in its pictorial form it is actually quite easy to follow. That is, if you go through it you can glean whatever interests you. Plenty to learn there. RF is something that CAN be measured unlike a lot of other supposed tweaks. However I'm sure that most of us don't have access to any RF equipment, Spectrum Analyzer etc.
      A well designed power supply is designed to deal with RFI, pollution from getting in or getting out. Unfortunately RF can find its way in through cables and inner connects and various grounding schemes too. Everything has to be treated differently, appropriately.
      From that PDF I learned that twisted pair speaker cable/wire was better at rejecting RF that straight side by side parallel wires. So from now on I'm going to twist my own speaker cables up pretty good!
    - AE Thanks for the link. nt - dmzwizard 06:00:47 09/01/11 (0)
