How to fuse bypass in Magnepan 1.7i


Anyone bypassed the fuse on a 1.7i specifically? I read that it's a simple move of the wires but this wasn't the case for me. As you can see in the first photo, the yellow wire connector is stamped to the fuse box, and the yellow wire crimped on pretty tight. I gave it some decent force and it wasn't budging.

I've also heard the Cardas small post works fine, but again this wasn't the case for me. The Cardas post was slightly too large in diameter for the Magenepan wire connector to fit over.

Anyone who has done this and could offer some guidance as to how you accomplished it?

Thanks in advance!

The problem with jumpers---no matter how good---is that the signal still passes through steel parts and junk wire.

My suggestion is use a pair of 1/8"x4"x4" aluminum plates drill some holes for new binding posts.

If you don't need bi-amp/bi-wire, connect all wires to one pair of binding post and no jumper required.

 

What I'm hearing is that maybe something changed in the past, what used to be a "10 minute unscrewing of the back plate and moving wires" now requires cutting the yellow wire to the fuse box and resoldering onto the post.

Given that, I might be out for this mod. I'm good with a reversible change of wires, but not so keen on cutting and resoldering.

LOL... you ain't no real-deal audiophile till you've irreversibly modded all items in your rig

The beauty of bypassing the fuse block is that it requires no permanent, irreversible mods (at least it didn't on my Tympani T-IVa). Just move the internal wires. Even if you very slightly enlarge the binding post holes to fit Cardas posts, the stock posts may be reinstalled, no harm done.
