Blown Amp

Kenwood amplifier has stopped working : ( Don't think it was being overloaded. Strange thing was, after it stopped working a display light was still lit, albeit not showing what it should have, but when I turned it off and turned it back on half an hour later, there was no display light.

There was a smell of burning bakelite, or similar. I checked the fuse in the plug and googled for some help. After a while, I dug out a spare amp and got on with some work. Hope I can repair it, especially if it turns out to be something fairly simple, like an internal fuse, but as it's around ten years old it might be difficult to get spares.

Reasonably good replacements are fairly cheap - but I'd like to avoid being a consumer.

What's more, it belonged to a good friend and has sentimental value.
