And, ummm, if your amp blows a fuse more than once, it's trying to tell you it doesn't feel so good inside. The engineers who designed it did lots of math to determine how much current the thing should draw, and how much is too much, then they put a fuse in there to burn up before your tubes, transistors, and worst of all, your transformers burn. For cripes sake, DO NOT short it out, or put anything else but what the engineers calculated! TAKE IT TO THE AMP DOCTOR!!! Putting a higher amperage fuse is saying, "Something's wrong with this machine, it's using more power than it can safely handle. Maybe if I feed it even MORE power, I'll never need to have it serviced," and you might end up being correct. And the engineers who built it will be sad, and the salesperson you buy it's replacement from will be stoked. And that's really what this game is about, right? Happy sales people.
