Plug-in parallel mains filter

Below are some images of a plug in parallel filter I built using the circuit detailed at Triode Systems. However, instead of trying to cram everything into a standard mains plug I used a "wall wart" power supply case. I built five of these for around £18.00 and have them plugged in at various locations around the house.
