Which SR Blue or black Fuse

I've had plenty of fuses blow because my amp has a massive power supply and the most basic in-rush current limiting. I've gone through about half a dozen this year. 

If you need a reference from a tech who's fixed the damage exotic fuses have caused, talk to Ramtubes. 

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,
