    I have an old tranny Hughes and Kettner attax 80.

    Would playing an ipod through it cause it to wig out?? Power on but dead to the world. The preamp fuses are ok...

    Thanks

    He played his iPod through his amp and it's no longer working so he's asking if doing that could have broken it, nothing confusing there I don't think.

    To the OP, I've played mine through my amp a few times n nothing bad seemed to come of it but I'm not sure, maybe someone else can be more helpful.

    i can't see how it would... the power flow from an ipod can't be much more than that from a guitar... i think a guitar drives more power tbh.. i found a post about it on another forum though.. might help...

    A headphone output contains a small amplifier, it could put out at least as much juice as an active pickup preamp if not more.

    A guitar pickup signal is in the frequency range of around 65hz - 5,000hz, and this is what a guitar amp is designed to operate with. An ipod would be capable of putting out anything from 10hz - 22,000hz.

    At correct level, I'm sure you can safely do it for any amp, though it's always going to sound like the music is coming through a blanket because the amp speakers are incapable of reproducing frequencies above 5khz. If you crank the ipod sufficiently, I'm also quite sure you can damage an amp.

    I don't know anything about transformer amps generally, or that particular amp, so I couldn't say if it's likely to be any more sensitive to a high voltage low frequency input signal than any other. Can you tell us more about the amp? I'm not sure what a "preamp fuse" is supposed to be, but the odds of overdrawing current in the preamp specifically before anywhere else are not high, so it's probably the last fuse that's ever going to blow for any reason. I'd check the other fuses. There should be a fuse directly after the "mains" fuse that's somewhere on the secondary of the power transformer, or after the rectifier. If a fuse is gone, this is the most likely one.

    Really, if you plugged an ipod into it and it then "wigged out" having never wigged out previously, it's probably reasonable to conclude that, indeed, running the ipod signal through it caused it to wig out. :pac:
