ok guys, im trying to put together a mains filter. well 2 actualy, one for pc, the other for entertainment system.
got myself some x and y caps, and a few mov's. question is, related to winding a choke.
is there an optimum number of turns?
is it better to have both coils on one ferrite ring, or seperate rings?
(if im remember here, one is wound clockwise, the other counterclockwise)
ta
