IMPORTANT NOTICE: A blown fuse is NOT the sign of a defective item – they are designed to do just that. We suggest that each customer test any fuse purchased for continuity, before installing in their gear, to ensure it is intact upon arrival. Also, given the cost of audio-grade fuses, it may be prudent to slightly uprate the amperage, to ensure that these expensive fuses do not blow prematurely. Remember, a blown fuse is not covered by any manufacturer’s warranty.
Frequently asked questions.
Q: Are fuses directional?
A: Yes, fuses are directional. Electricity should flow from the left to the right when you view the fuse. If you do not know the direction of flow you should listen to the fuse inserted in both directions. One direction will sound more detailed. This is the correct way.
Q: Do fuses have a burn in period?
A: Yes, most products have a settling in period. The first 200-300 hours of use are the most crucial.
