      Thank you both Florian and Alan,

      your help is very much appreciated. You are right, Alan, first the external transformer to check there is no problem with the synth, is the right thing to do at first.
      Then a bit of sweating over schematics and off (soldering) I will go!
      At the moment, I am comparing the schematics with what's inside the synth...

      Again, thank you!

      Sophie

      > But I would suggest getting an external transformer before you try anything else.  If you were to change the internal one your self or even have someone else do it for you at cost and you then went on to discover there was something wrong with the internal workings of the synth you would have no way of knowing if the problem was present before the power supply was changed.
