Can anyone recommend a good place to buy replacement fuses (for subs)? Also - are there really 250V fuses (as opposed to 120V fuses)? Radioshack did not have the 0.6A fuse I needed, and I want to test to see if my sub has a more severe problem than simply a blown fuse.

Much thanks in advance!

There are indeed 250V fuses. If you can't find one at radio shack online, let us know and we'll send you one. (1-877-TO-AXIOM, ask for Joe Vassallo)
