Default stacking toroid chokes

Is it possible to stack multiple chokes on top of each other in a p/s since they would have have little stray magnetic interference on their neighbor?

That is something I plan to test at some point.

Yes, its one of the advantages of toroidal inductors and transformers, not needing to be spaced far apart. There will be some leakage of course, you wouldn't stack a signal transformer on top of a PSU choke for instance, that would be asking for it.

There may be a concern with parasitic coupling of capacitance for the situation where the chokes were electrically connected in series.
