I was playing it the other night on full volume with a drummer and it just went out. The red light was still on but no sound was coming from the amp. After I got home I plugged it into my computer and it works through my computer speakers. It seems like the problem would be from a blown speaker but.. i dont want to buy one and find out it was as valve or somthing.
That sounds like a speaker. Take it to a repair shop to find out.

check the connection to the speaker, if you blew the valve it would not work with the computerspeakers.

Edit: I don't think you could blow a preamp valve, not sure though.

probably speaker. but playing regularly at full volume is gonna break pretty much any amp at some point.
