Ashdown ABM500 EVO III is buzzing : normal?

    I just got got a brand new Ashdown ABM 500 EVOIII RC.

    It produces a slight buzzing (not humming) through the cabs when running, wether some cable is plugged in or not, wether the mute button is pushed or not, even when the master post is completely turned down.

    I once had an EVO first generation, but I do not remember if there was abuzz with that amp.

    Might it be because of the fan?

    Has anyone noticed the same?

    Shipping the amp back will probably get expensive.
    So I am trying to avoid the "this is normal with this amp - answer" by the online seller.

    Mine has a slight buzz too. Nothing more than I'd expect from an amp though. However it does make a popping sound every now and again, which is VERY irritating. Also it's currently in the shop to fix a broken mute-button for the second time since I bought it (summer '08).

    I love the sound, but I'm not impressed by the quality...
