Does Playstation SCPH 1001 NTSC dual voltage?
I just bought a SCPH 1001 NTSC playstation 1 today for only collection purposes. I wonder does it work on 220V like PS3s ?
It depends on the region, since they are region-locked. If you live in, for example, the USA, your PlayStation must be the U/C region model or have a 120v power supply. Check the region of your PlayStation, if it matches your region, it shouldn't spell disaster unless some idiot replaced the power supply with the wrong region.
And no, they can't do both 120 and 240 volts (since they are region locked). If you want it to handle 240 AND 120 volts, you'll need to get a custom made power supply board.
