What are fuses used for?

I almost forgot. Fuses are also used to torture naysayers. That’s the most fun feature of fuses as we have seen.  Fun for everyone! 

“Contrary to popular misconception by the ill-informed fuses (like all wire) have NO effect upon sound quality. To think otherwise is to believe in magic!”

Here we go again.....hope this thread doesn’t turn into heated debate on the effectiveness of aftermarket vs. stock fuses. 

Where do you put the fuse????

If you have the manuals for your equipment it shows you where to replace a fuse. If you don't have the manuals you can probably download them from the manufacturer. 

Thank you very much.
