    Looking for someone who has successfully converted a mesa 400+ from 110v - 240v, I have done plenty of searching but cant find a definite answer.
    im from Australia and have family in the states who can get me the amp a lot cheaper . They retail for close to $5000 Australian dollars so there is a huge saving!...any help would be great

    cheers

    I think that you can switch 400 for 230V but not 400+. I'm afraid that current Mesa amps are not convertible and you would have to change the whole transformer.

    I've tried to ask this question directly to Mesa some time ago and I didn't get the answer. Maybe you can try to mail or phone them?
     
  3. Yes it can be done- the tranny is tapped like on the 400.
    I have the schematics

    PM with request sent :)

    Does anybody have scheme of Walkabout, M-Pulse or Big Block? I don't suppose, but that would be nice :)
     
  5. Emailed you Kris.

    AFAIK the 400+ is the exception to the rule. You're right- the other new Mesa amp transformers are not tapped for easy voltage conversion.

    get a 110 / 240 outboard transformer instead
     
  7. my mesa 400+ was bought from the states and converted from 110v to 240v by a mesa engineer here in scotland with no problems whatsoever.

    Do it, its a great amp.

    It can be done and it's quite simple - if You know what to do. I got the schematics from MESA (I e-mailed them) and a local tech did it in no-time. There are (literally) 3 wires and a fuse.

    hi!

    Could anyone of you send me the schematics for the conversion to 230V?

    Thank you so much for support!
