Which SR Blue or black Fuse

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,

Yes, why can’t the  "same " trolls let the fuse folks have their fun. Why must they show up, over and over and over again. This is a hobby. Enjoy ! MrD.

" I have had plenty of fuses blow because my amp has a massive power supply ". Many amps being sold have massive power supplies, and if fuses were to continue to blow, I think these amps would be right back to the manufacturer for constant repair, or replacement. Enjoy ! MrD.
