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!

@jjss49 Totally fair question. The wiring of the Maggie's are their weakest part. The fuse and attenuator in particular use low quality parts and there are many steps a signal has to step through in order to make it out of the speaker. Many have found that bypassing the fuse results in a much clearer, brighter sound. As long as you don't listen at ear-splitting levels or have an amp that can't keep up with the Maggies, there's little chance to blow the fuse.

Lots of people also use a copper tube in place of the fuse, which is my back up plan, but I'd rather bypass this low quality wiring altogether.

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.

@bdp24 On the Magnepan 1.7i, it does require an irreversible mod. You have to cut the yellow wire going to the fuse block, and then resolder it to the post.

Thanks @imhififan ! I tried getting the spade connector off but will give it a hold with pliers. Need to source some male connectors as well. Will report back!
