A year ago SgtWookie & JFairman had an interesting thread about a choke design to filter out noise generated by a headlight modulator (240Hz switching of a 12V, 100W load). SW came up with a toroid recommendation using something from Goldmine - but that toroid is no longer available and had pretty unusual characteristics (Al of 9,900).
Is anyone familiar with an analysis of this type who can help suggest another toroid that will work in the circuit? Here is a link to the original discussion:
