Malka insert a 1 ohm resistor direct after each rectifier. The peak currents introduce current spikes which in turn creates EMI.
I always use 300uH direct after all rectifier briges before any electrolytics.
toroid inductors is good since the leaking field is low.

Thank you, Salas. When I'm late to the party, I want to check the invitation to make sure of the correct attire.

It's a Goldpoint.

Westend built that beauty for me! Can't wait to get it hooked up to my F5 monos.

I've forgotten how you edit over here at DIY but don't follow my depicted mistake, above. I don't know what I was thinking but I managed to get the input and output wiring reversed. It is now oriented correctly.

Strange thing, I was driving along and was thinking about this project when it dawned on me. When I got home I brought this thread up and looked at the first attached picture from my previous post. Yup, I are backwards.

Attached is a picture of the finished case. Mr. Fud is going to like this, methinks.
