  •  It is a 100v Japanese model and will run fine on North American mains 115/120v without a transformer (we run all our tests using 120v power); however, a step-down transformer is recommended for extended use.
  • A step-down transformer is required in the UK/EU.
  • We do not recommend using cheap generic Chinese mains transformers and can supply a high quality UK-made unit if required.
