Hey guys. I was just wondering, what reasons can there be for a blown fuse (talking about amps)? Is it caused by tubes? None of mine are blown, although I did notice one of them didn't have the part of the plastic that plugs into the amp (the one in the center). Instead it just had that small glass bubble thing. Could that be it? Are there other reasons? Anything would be appreciated.
A fuse blows when too much current passes through it. That could be caused by a power surge (from lightning or something) or, for example, a tube failing, causing the amp to try and draw too much current.
