Default Mains Filter/Conditioner

Hi All,
Some years ago I had a diagram of a mains conditioner made by good old Maplins.
It had a handful of caps, 7 or 8 VDRs and two encapsulated RFI filter back to back.
I’m rearranging the system and thought I might use one. Just a thought
Does anyone have the circuit? it was a free Maplin project
Thank in advance
Martin

Hi Martin, this sounds very similar to the one from Hi-Fi world magazine, I built one and it is still in use but, I don't remember it making much if any change, I will try and copy the parts and circuit, from memory it composes X2 and Y capacitors, a few resistors and two chokes fitted back to back all on a tag board.

Thanks Bob yes it does sound like it. I donít remember the HFW one myself but it sounds very similar.
The Maplins one was in a box with one outlet but you could use a multi socket extension off it or of course build it into a multi socket box. Providing the RFI filters power rating was observed.
Any info gratefully received
Thanks Bob
Martin

All of the Maplin magazines are on the 'worldradiohistory.com' web site, free to use.

You want July 1995 page 24...
