Hi! I've got a few schematics of the System 100... but not of the mixer. If you want me to, I'll do the calculations for your transformer. But if you want a more simple solution, buy a step-up converter that will take your 120ACV 60Hz to 240ACV 50Hz. Those are easily available. Just Google it up to find the nearest dealer.
