    Hi guys,
    I have just received a GK 700rbII from the states and require a step up transformer as I am in Australia. Averages 230 watts and peaks 994 watts. Will a 1000W transformer be suffuce?

  2. You mean step-down transformer...? (I know, turn it around, same difference.)

    And, yeah, 1000W should be fine.

    It must be a terminology thing that has me confused. I will be plugging it into 240v so don't I need it to step from 110v up to 240v?

    Sorry I'm a newb


  4. mate- get it looked at. I think the II series can be internally rewired. I know the 1001RBII can be.

    Yes, check the user's manual. It might be a simple fix and save you the considerable cost of an adequate transformer.
  6. Well, the wall powers the amp, not the other way around. :p

    Like the others say, check if it can be adjusted internally. Switched-mode power supplies are usually more forgiving with different mains power.
  7. It won't be switch mode but will probably be multitapped. Similar to Ampeg Pro, Aguilar and Eden heads.

    The power consumption should be stamped on the back of the amp, in watts. This you must meet or preferably exceed with your step-down transformer. Note that the transformer will most likely be rated in VA. I would think that 1000VA should be enough. It'll be heavy for sure.
