Littelfuse has been around since 1927, designs award winning products for thousand of applications, and their fuse ratings are absolutely accurate...the fuse for my amp is superb and cost around a dollar. "Special" fuses add nothing to the sound of a component, and, as in the case of a pile SR fuses I tested a few years ago, it seems SR can't even properly rate their fuses. Avoid these.
Synergistic Research Orange Fuse
I have purchased this fuse for my line stage and power amp with great results. I would like to purchase another for my integrated Tube amp, however, this amp calls for 15A and SR only has a 16A fuse. Will this cause damage to my tube amp if I replace the fuse with a higher rated fuse? Thanks for any help.
