Ferrite chokes offer a lot of inductance in a small compact package. Providing they can handle the current is there any reason why they can't be used as chokes on the DC side of the supply?
Phil,
Nope, inductors are inductors. Once you've got the current covered, you should be set to go.

The ferrite chokes used for DC are different then the other ones. In ordinary ferrite chokes the core saturates by the DC and choke doesn't work as an inductor any longer. The core must be of two parts, isolated of each other. I don't know what the correct term in English is. In my language we call it "air intermediator".
I hope this will help.

That is true a choke for dc that uses a core of some kind needs to be designed for dc work. I think the right term is air gap. It separates the two usuall parts of a trafo so it doesn´t form a closed loop for the magneticfield. The same design is used in output transformers for single ended output drive.
