Blown Fuse?

On Wednesday about half way through a 2 hour practice, I set my guitar down and walked away for 10 minutes or so. I am not sure if I put my head into standby or if I just hit mute on my pedal. But anyway, when I came back the amp was dead. No lights no nothing. We pulled out the fuse and while it did look kid of fried with a definite discoloration in the middle, the element was still in tact. I'm not really familiar with this type of fuse but most I thought, work by severing the connection in the element. But anyway, I ordered some replacements and a new rectifier tube as that is what can cause a popped fuse from what I've read. I don't think its an electrical issue in my house as it is new construction and I have never had an before. Im hoping it's just a bad rectifier tube. I have never replaced that one in the few years Ive had my V.

If you don't wanna wait and have a Sam Ash that's close by,
they have the right fuses.

I think power tubes can cause a fuse to blow as well as
power surges that can happen even though electrical
can be new.

My fuse blew a while back. I swapped out all the power
tubes, inners first then outers, nothing. So I put the first
set of power tubes back in and I've been running 'em ever
since (through gigs and rehearsals).

So, I chalked it up to an electrical surge. I talked to one of
the studio guys and he thinks there's something funky going
on with that electrical circuit my amp was on when the fuse
blew.

Since then, I've started using one of those basic power strips
in hopes that it'll catch any weird power surges before hitting
my amp.

Good luck!!

Ya actually I ordered the fuses and an electro harmonics 5u4gb tube from parts express on Thursday afternoon. They are in Ohio and me being in Michigan, I got them the next day. Popped both in and it fired up no problem. So, who knows if it was actually a bad tube or surge or whatever. The weird thing is I just recently got a decent power conditioner. Also my power tubes are new within the last year so, idk. If I blow another fuse in the near future I might take it in for further investigation.
