Help with blown amp


I have a Plinius SA-102 amp which I have had for a few months. It sounds great and I have never had a problem with it. This evening, I was in another room, not listening to music. The amp was on as always, but no music was being played. All of a sudden I heard a loud hissing sound which lasted for about 3 or 4 seconds and then a click. The amp has an automatic mute switch which kicks in when there is a problem. When I checked out what was going on, the mute switch was on and I could smell burning plastic. The mute switch will not go off, and the amp will not work. I immediately unplugged the unit and tried to remove the top lid (per the instructions) to see if one of the fuses has blown. Unfortunately, I can't unscrew some of the allen nuts as they are too torqued.

Can someone please help me get a good night's sleep and tell me that it's only a fuse? Could it be worse? Any ideas on how to get overtorqued screws out?

Any help would be greatly appreciated.

All i would add to this conversation is that non-mechanical equipment failure is not normal, especially for a new unit. If the unit was 10+ years old and it went dead, i would not think too much of it. The fact that you leave the amp on and have reduced thermal cycling to a minimum and the amp has still developed a problem might have me worried about future operation.

Let's hope it was something simple and just a faulty part. Hopefully, you've got another amp to fall back on so that you won't be "tune-free" for the long weekend. Sean
