    Got a bit of a problem with my amp - I've just seen it catch fire.

    I've spent the evening attaching my new speaker cable and banana plugs and at first everything seemed fine. Watched a bit of TV, played about 30 minutes of XBox and all played fine. I was then playing an MP3 through my PC (Nick Cave if anyone's interested :)) and, again, it played it fine - right until the very end when I heard a loud pop from the speakers.

    Looked over at the amp and the red light around the power button was flashing. Had a look at the connections and everything seemed fine so I turned the amp back on when this time the amp went pop and you could see something burning inside. This only lasted a second but you could smell it afterwards.

    I can't see what I would have done wrong wiring up the new cable, it's plenty big enough for my set up and whilst I've never used banana plugs before, they don't exactly seem like rocket science. But then again, it seems a bit funny to be just a coincidence.

    So, what do I do now? Will this be covered at all in any warranty? Is there any chance I could have knackered my speakers as well?

    Sounds like something has shorted out inside. It may have been the result of you making connections on the back i.e. pushing in the banana plugs could have dislodged the board they're attached to.
    I have previously caused an amp to shut down by accidentally shorting the speaker connections with a stray wire. As you're using plugs this is less likely but I assume you were removing bare wire so you might have left a small thread of wire in the connectors.

    If I were you I would check the speaker connections very carefully for stray wire - if you find some then you will have to make your own choice about what you say to the dealer. If not then it's gone pop under warranty and should be repaired free of charge IMHO.

    I should be checking for wire connecting the red and the black on each channel?

    yup, have a look for stray bits of wire; could be something internal blowing as well, though. If it's something you did (e.g. shorting the speaker outputs with stray bits of wire) this is unlikely to be covered under warranty, although you could either try asking the dealer nicely or forget to mention this ;)

    Anyway, if it's something internal blown/not your fault then that should be covered under warranty :) Even if putting in banana plugs made it go, an amp should be designed to take such plugs without blowing...

    btw, the nick cave you were playing - not 'babe I'm on fire' by any chance :D
