Is My System Toast?

Does the amp still power on? It sounds like it does if you can switch the input to CD. You need another pair of speakers to confirm if both channels are still working. Replace the fuse, if it does work, just for the peace of mind of having a newer fuse.

If it is confirmed the amp is dead, what a great opportunity to upgrade, and nobody can tell you "no" :)

Like others have said, check and most likely replace the fuse in your amp. Then you’ll know how to proceed.

All the best.

Last resort is to check with your home insurance company.

I do like my furman 20 I. In the west we have many power issues and so far it has been good to me. It has an extra 60 amps in storage capicitors  for transients in big monoblocks.  There have been great suggestion above. Find another set of speakers at the salvation army and test away. I always plug my new used amps into cheap test speakers in case there is something wrong. You can use an ohm meter on the back of the speakers and look at factory specks.make sure not open or direct short. Checking and replacing the fuse is a good thing. Best of luck.

What a bummer Dude , sorry. Some good advice here. I can only say for the future I live up in the mountains of So. Az. with a small power company and we do have outages from time to time . All my gear is on strip protectors and they are completely switch off unless in use. When out of town which is frequently , the strip protectors along with most everything in the house is unplugged including the internet router which runs hot enough to cook a turkey on.
