  • Recent Vox AC30/6 TB w/Greenbacks - problem?

    I just got one of these on ebay, and the thing looks perfect. What I'm wondering (from anyone else who has one) is if anyone else gets a good amount of noise from their amp without anything plugged into the amp. It's a late British model with greenback speakers, and I can have nothing plugged in, or my guitar, turned up or down, and when I touch the volume on the amp, it buzzes. Is this normal?
    I appreciate responses.

    Uh, can anyone help me out? It seems like the brilliant channel is buzzing more than anything else, and there's a light hum with all of the controls turned down, but it amplifies a lot when i plug into the brilliant channel.

      i had one like that myself... it was quite noisy, but i cant say from your description if the amount of noise you're getting is excessive.

          Had the same problem with an AC30.One of the EL84 had a failure.Replaced all 4(you should change all 4 because they should match.After replacing them problem was solved

            Filter capacitor could be weak,.
            Wiggle the tube buy tube then try swapping preamp tubes.
            Unplug all effects loop chords if any and this what i would try,   and plug the 120v cord into a cpu power regulated power sockett.
            The input jack my be the switching type and be dirty on the contact,i think its just a spring steel contact problem !
