" 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.
50 years, 100’s of amplifiers, never a blown fuse.....Go figure. Well, not really true. Once, and only once, I was very stupid. Enjoy ! MrD.
I hate to judge too quickly but apparently only trolls blow fuses. Would that be a fair statement?

Hey... If you don't believe me about tuning fuses frying stuff, listen to a guy who's seen it.  
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.
