I have acquired a Playstation 2, model "SCPH-55000", i.e., an "NTSC-J" model. It has an internal power supply: the power cable is simply a cable, not a transformer. All of the documentation, both in the manual and on the device itself, says simply "100V", and not "100-120V" or "100/110V", as hardware sometimes does.
Is it safe to run this on 120V? (I know a 120->100 converter is pretty cheap but not needing one is even cheaper.) That is, will it work, without catching on fire, and without significantly shortening the life of the hardware?
