Original poster: "Jason Petrou by way of Terry Fritz <twftesla-at-uswest-dot-net>" <jasonp-at-btinternet-dot-com> Hi all, How do I build my own line filter / RF choke to go between my tranny and the rest of the cicuit? I am using a 9/30 NST (weak-ish i know) and i want it to last as long as possible without any problems. Thanks, Jason
