I recently got my 5150 biased, and had played on it a few times with no hitches until now. I was jamming, and all of a sudden the sound gets muffled and the amp sound like it changed to the clean channel, crackled and turned off. All within a matter of seconds. The amp had mesa boogie tubes in it. I'm not really sure what the problem could be, maybe a internal fuse? But when i would play on it, i would notice the tubes getting really warm and a slight odor. But i just attributed it to the tubes running warmer now. Any suggestions before i take it into the shop where i got it biased?
Thanks.

If you just had it in a shop I would take it right back. Were the tubes new? New tubes can sometimes fail right off the bat. The amp doesn't power up now? It could be several things. Did the bias mod just get done? It may have been done wrong. There's several fuses inside the amp. You may have blown one. but you'll need to find out why it blew before just popping in new fuses.
