I am very old and losing memory. I don't remember the name and how it looks anymore. I have both a D250 and a D255 and always use the D250 due to lower sound from Fan running. Now I need to have them both going so I need to find the power supply for the D255. How do I know which one it is. My basement is full of powersupply and which one is the one for D255? Any model name or number or specifications that makes me find it by reading on the plates on them I have? Replies appreciated! Edit. Ooops I forgot to tell. I live in Sweden so most likely it is a power supply that can use 230 Volt in and live up to European Union CE certificate of safety something?
