Starting with the preamp tubes (with the amp OFF, and the tubes cold), replace one at a time, see if the problem goes away. If you don't have any spare tubes laying around, a cheaper, faster, easier way is to just move the preamp tubes around to different sockets. Since each tube has a different function, it's possible that a tube could be bad in one position and work fine in another position. But if you have no sound at all, I bet you blew the fuse.
Of course it's possible that a resisitor, or capacitor, or other component died, but the tubes are the easiest to check, and the most likely culprit. Hopefully the transformers are ok, they're expensive.
