Which SR Blue or black Fuse

I had a Hifi tuning fuse  blow up for no reason  A few years back. 
 Why bother taking the risk, even if it’s minuscule, for absolutely zero gain? 

Sounds like operator error. No offense. There’s a reason for everything.

 You’re right, I probably installed in the wrong direction! 😁

Here's a perfect example of why that other tread was shut down: the hyperbolic, over the top, harping fish wives are taking residence in yet another fuse thread to wreak their havoc. 😄

All the best,
