    Default Mains Filter

    A two stage feed-through filter (AKA 'Swampy Filter') in the making.

    I need to find a box for it as the one I bought (it's sat on it) is a bit too short. Bloody boxes are the bane of my DIY life!

    I've had the bits sitting around for ages but I'm off work for two weeks so I thought I'd start getting some stuff done. Built a AES/EBU cable today too...

    Hi Mike, are those common mode filters (chokes) you are using? Just asking as i'd imagine that normally these would be displayed as two windings sharing a common core. From what i can see this might not be so..

    Will probably work fine seeing as you are going to feed them unbalanced mains, hope it works out for you & benefits your setup

    Gotta love DIY, stuff paying loadsamoney for something you can possibly make yourself for vastly less

    Keep up the good work!
    Bests, Mark
