I was playing Led Zep's How The West Was Won on DVD using my X1 for side surround duty when I noticed the power light was off on it

I could not get it to come on, so this morning I pulled it from my rack expecting the worst while hoping for the best.
Took out the fuse, but it was a ceramic type so I could not see into it.
I took it down to RS to see if it was good or not. It wasn't
I bought the old 4 pack and am now back in business.
I guess the old fuse just gave up the ghost after 25 years or so.
We did have a storm come through last night, but there was very little lightning. I wonder if I got a large enough spike that it didn't bother anything else but that old fuse????
Anyway I'm in a bit better mood now that it's working again.
