Which SR Blue or black Fuse

If you’re foolish enough to waste good money on boutique fuses, add an additional real fuse in line with the boutique fuses so there’s some real protection. Boutique fuses aren’t UL or CSA approved or tested in any meaningful way.

PADIS fuses are UL, PSE and SEMKO approved and they are "boutique" fuses.

Thanks for responses. I believed fuses may blow, they would not be putting them in otherwise, but was wondering how common that really is. I guess more common than I observed. Maybe mrdecibel and I are simply lucky.

In my case the blown fuse was a little bit of user error as well as a little manufacturer error.  I was listening pretty loud when I switched on the fly from the triode to UL, instantly doubling the watts.  Later in discussing with the manufacturer, they recommended using a 4 amp fuse instead of the 3 amp fuse that came with the amp stating that you can usually get away with a 3 amp fuse but switching surges can sometimes pop the 3 amp.  Since then I always reduce the volume when switching from triode to UL and have never had a problem since, even with a 3 amp fuse.

I never had a fuse blow in all my years in this hobby.
