Is there a solid fuse-like item that I can use in place of a fuse, to bypass it?

Shear is a component of all vibrating surfaces.. Speakers, walls, violins  cellos their strings and bow vibrate and generate shear just like a fuse vibrates when its host is turned on and running. Tom

@theaudiotweak you can state facts. But fact which are not germane to what we are discussing is smoke-n-mirrors stuff.

It is appearing that you are spruiking total BS.

I bought the Magnepan  by- pass solid silver tubes from OCD Mickey.

I had to cut and polish  them to suit my fuse holder and treat them with contact oil  in my Elac Navis active speakers.

Very Nice

UL certification is not legally required in America. 

There may be commercial considerations, and perhaps some codes may require it, though.

I understand that Underwriters Laboratories is a non-profit organisation dedicated to testing the safety of electrical products.
