    If downunderwonder or anyone else could chip in with a pic, simple diagram or a bit of a more detailed explanation for us amp guts noobs I'd be very grateful as I'm heading home downunder this year n wanna bump mine up to 240v without screwing it up! Thnx heaps!
  2. Mine is different from the pics I found on here. Opening up you will see the markings for 120v/240 or whatever it is. The centre pin is common. You will see the "spare" pin for 240v and the jumper.

    I made a hook from a paperclip to yank the jumper clip off the 110 side, replaced on the 240 side, job done. I didn't like my chances of crushing the clip using pliers.

    Cheers sir, much appreciated. I have a MIC model with the combo speakon/1/4" jack I bought about 2-3 yrs ago from the US; it works fine here in Japan n wanna keep it that way in Oz n as you know, we pay top dollar for any import amps in NZ or Oz. Cheers again!
