    To set the voltage for different areas around the world, remove the two screws that attach the Voltage Selector Cover Plate, located at the far left, above the AC input connector. A voltage setting guide is printed under the plate.

    To set for 100 volts (Japan) the top switch should be set to 100V and the bottom switch set to +0V. For 120 volts, set the top switch to 100V and the bottom switch to +20V. For the EU determine what your actual voltage is. Although the EU has “standardized” on 230 volts, countries still run between 220 and 240 volts.

    For 220 volts set the top switch to 220V and the bottom switch to +0V. For 240 volts, set the top switch to 220V and the bottom switch to +20V. For 230 volts, set the amp to operate at 240 volts.

    FUSE: If you change from 100-120 volts to 220-240 volts, or back, you need to also change the value of the Fuse. The fuse in the TFB550-B is an American 3AG size slo-blo rated at 8 amps for 100-120 volts, and 4 amps for 220-240 volts. All amps have the fuse size and type printed on the back of the amp near the fuse holder. You should always check the voltage selector switches whenever you’re unsure of what the amp is set to. They are located under the cover plate above the AC power cord connector.

    SHORT ANSWER: Yes.

    I believe the amp comes with a voltage converter switch, covered with a steel plate with Dave's signature on it. It's located on the back and on the very left part of the amp. I might be wrong, though.
