J'ai fait ça il y a quelques temps sur une 5100. Me suis fourni là :
Redresseurs MBRF20100CT (10 pièces)
Condos 330µF 450v cap 35x35mm (10 pièces)
Mais comme dit sur le serveur Discord PS2 Scene, il y a surement de meilleures sources pour ces deux composants...
Une copie du post original de Lonedone sur ASSEMblergames :
Lonedone a écrit :Hi, everyone.
Original japan psx console will not work with euro 220 V standard outlets. And i really hate to use additional big 220 V -> 110 V transformers because most of switching power supplies require a bit of modding to be able to support 220. There is that i did and it works just fine, wanna share it with you, maybe it will be useful for someone.
1) С005 1000uF 220V should be replaced. I used 330uF 450V bought from ebay, it have exactly the same dimensions.
2) To disable overvoltage protection remove zener diode ZD001.
3) Strongly recommend you to replace D201 diode, cause oscillogram of the transformer secondary winding shows a bit of excess of diode reverse voltage with 220 input. I replaced MBRF1060 with MBRF20100CT, it have 3 pins opposite to MBRF1060, i just cut out left pin and wired up central.
Good luck.
Ça fonctionne de mon côté. Si quelqu'un pouvait confirmer que c'est électroniquement OK...
Le 220 conviendra très bien
