Why would the fuse blow on my amp???

Recommended Posts

I've got an Ampeg Reverberocket RI (1X12 50W combo). I recently replaced the power tubes because they were starting to fail (making a low freq. hum, weird blue-ish glow), set it to the same bias value that I always set it. Just last night, it dies on me (BONUS - during a gig, not even halfway into our second song :facepalm: ). I opened up the back panel and found that the fuse had blown. I replaced the fuse, turned the amp on without anything plugged in, and everything SEEMED to be in good working order again.

 

So... anything else I should try (other than plugging in my guitar and playing it for a while)?

Should I have replaced the fuse as well as the tubes in the first place (perhaps the fuse was on its way out too)?

Anything else I should be worried about?

Maybe the original fuse was just ready to go. No way to predict these things. If the replacement doesnt blow again, you should be fine.

I'd replace the fuse and fire the amp back up. If it happens again it's very likely a power tube went bad.
