So I purchased a Sharp FT on eBay. It came with some third party power supply. The system plays for a bit then just randomly resets or powers off. Sometimes it will not even power on. I did some research and it seems these are really picky with what power supplies are used. I looked and it seems the one that came with mine is 9v and needs 7.5 volts. I bough one off Amazon that is 7.5 volts but I think its wrong as it says 3A and this needs "1.25" A whatever that means. Can anyone recommend a working power supply replacement for this before I spend big money importing the OEM one from Japan? Any help would be greatly appreciated. Thank you.
