So today I was messing around with the SS/Tube rectifier and Bold/Spongy switches, going back and forth to get a feel for the differences in tone. Then, at one point I switch from Spongy to Bold the power cuts out. No smoke, no funny smell, and no weird crackling sound at all. And AFAIK, the powertubes didn't display any arching or other anomalies. At first I thought perhaps the powercord simply came loose. Tried re-seating it, but no dice. So I popped out the fuse, and sure enough, it has a small burn on the glass. Nothing too servere, but it's toast obviously. I have no spare fuses on hand, so I'll stop by the shop tomorrow and pick some up. I've got my fingers crossed though...
Which leads me to my question. I've never had a fuse blow on me, but from my understanding it's sometimes a symptom a bigger problem. Should I be concerned?
Also, should I switch to standby before messing with the Bold/Spongy settings?
If you replace the fuse and it blows again, I'd say that's a symptom of something bigger going on, but you know, sometimes shit just dies. I'd just replace the fuse, and then if it fucks up again, take it to a tech.
