Japanese SMS question: Will I need a transformer?

Hello. I purchased a Japanese SMS (not Mark III) online because I wanted the built-in FM Sound Unit, and am currently waiting for it to arrive. I live in Brazil though, so do I need a transformer to make it work here, or will it work fine right off the bat? | |

Power supply in Japan is 100v and has both 50hz or 60hz depending on the area.
Google suggests Brazil is 127v at 60hz. The voltage might be a little bit high for a power adapter designed for 100v. Normally +/- 10% is ok, but you would be 27% high, which i would suggest avoiding. Im not sure youll easily get a step down transformer to go from 127v to 100v. Its probably best to use an existing master system one that you may already have. You can also use a modern replacement power adapter. Its output just needs to be 9v DC, 1A and center negative with a 2.1mm barrel jack. |

In general yes, use your local AC adaptor across Sega consoles. It’s best to check the polarity just in case. 9V vs 10V doesn’t matter. | |

I found this. Would it work?

I strongly recommend using a Triad international power supply instead. They're high quality, have been tested and "approved" by the MDFourier team and have been my go-to for a few years now. FireBrandX put together a nice page showing which PSU works with each console: http://www.firebrandx.com/triads.html | |

That Brazilian power supply with a DIN plug looks like a great way to fry something... for most of the world, the SMS has a barrel plug for power. | |
