So the proection circuit driving the relay detected high amounts of DC and did it's job - that's good!

I'm assuming the relay simply disconnects the speakers in the face of DC at the output. Did you have a load attached when you closed the relay? If you didn't, I'm trying to figure out how closing the relay would give a path to ground (and draw enough current to blow the power fuse). If you did have a load attached, I hope you didn't take out a woofer in the process.

Charles may be right - look at the output transistors, and keep an eye out for anything earlier in the signal path that might have caused an output transistor failure. Without a schematic or the amp itself to look at, it's hard to give much more guidance.

Good luck, and let us know how you make out.
