Hi,

Just to let people know that I have just put up a couple of new pages that
explain the basics of how mains RFI filters work. The aim being to allow
readers to decide which type of filter - if any! :-) - might be most
appropriate if they have a problem with RFI.

The first page is at

http://www.audiomisc.co.uk/mains/filters1.html

and that has a link icon at the end to take you to the second page that
deals with ferrite and VDR devices and their use.

Slainte,

Jim



From endless searching through catalogues, it seems to me that most
commercially available mains filters are aimed at trying to stop
equipment *transmitting* crap onto the mains rather that stopping it
getting in to equipment though I guess reciprocity applies to at least
some degree.
