I'm not sure, I was recording with master volume on about 7, when it made a monster sound. I had noticed it was lacking gain, so pushed it harder, when it fizzled out.
No bang or anything, just a noise then silence.
Being a rock n roller, I just grabbed another amp and carried on recording. Didn't want to loose my train of thought.
Now though I've got to start figuring out what's wrong.
I'll look tomorrow. Btw all the 88s light up, so I assume that means the fuses are ok.
