I currently own a Klipsch promedia 2.1 computor speaker system. However, the fuse blew and i can not find the specific fuse i need anywhere. The web site says that i just need a standard 2A 250V slow blo fuse, but the fuse that that orignally blew has a thicker filament then these. I even tried them and everyone one a tried has blown. This is frustrating me and i have no clue where to go to in order to find this fuse.

If a fuse blows in a Klipsch ProMedia 2.1 (2 amp slow blow), v.2-400 or 4.1 (5 amp slow blow), or 5.1 (5 amp slow blow 5x20 mm), there is a problem beyond the fuse. Replacing the fuse will not solve the problem, and putting in a heavier fuse is dangerous, and will cause further damage, if not a fire. In the 2.1 or 4.1, a blown fuse could be from a damaged bridge rectifier (easiest place to start, anyway). In the 5.1, a blown fuse could be a blown MOV (sacrificed due to a power spike), blown bridge rectifier, or shorted daughterboard and nearby IRF740 MOSFET(s).

Have you used 2A SLOW BLOW fuse? This type of fuses usually are ceramic type and are very different with the glass type ones. The glass type fuses are (more or less) fast blow. Although the best solution is to find SLOW BLOW fuses like this, in case it's very difficult you can use 3A fast blow fuse also.

In case of a problem or clarification, don't hesitate to post me a reply before rejecting my answer.
