There are several items on the list from it. The coils I wound are about 1" long and 4 inches in diameter and are glued in place with epoxy. When I build my own amp, the filter will be in with the final, and will be using the ferrites for a size reduction to make that possible and to limit stray pickup. Later today, (It is 5:00 AM) I plan to follow those of your ideas out which can be addressed now. Jim and All On a separate vein, I have some torroid cores removed from switching power supplies which are yellow with white (-52?), light green with blue (-26) and solid dark green (??). Are any of these materials suitable for use as the SWR protective transformer core? Thanks, J
