[QUOTE="jeallen01, post: 1090880, member: 176704"] That internal PSU is on a separate PCB/PWB with an easily identifiable DC o/p connector, and thus fit a suitable i/p socket in the case with a 2-core cable between that and the PCB/PWB connector - the issue is to determine the o/p polarity of the board connector, probably by tracing the rectifier(s) and large smoothing caps in the secondary ccts, and then how they connect to the board connector. OTOH, one can probably find, online, a 230/12VDC ( I very much doubt that the main circuit board requires anything other than 12VDC) PSU PWB/PCB with the same dimensions as the original, and fit that in it's place - still has the polarity issue though. Edited: Just read istvan's latest post - MORE complicated, but boards with 5V/12V/24V outputs are almost certainly obtainable. [/QUOTE]
