Wow, the processor, network interface, display and spdif output still all work?! I think you are lucky. As far as I can tell no schematics are available. (This part of the slimdevices design is not open source like the server.) However I've noticed that "seanadams" ( profile: http://forums.slimdevices.com/member.php?u=3) said this: "The full schematics have never been released. However, I'm usually happy to answer specific questions." in this forum: http://forums.slimdevices.com/showthread.php?t=31187. Without the schematics I think people can only guess at what happened. If you back drove 3V or 5V logic with 9V you might have presented 9V to everything. Hence why I'm surprised anything works. But I would have guessed the logic (i.e. processor) would have failed before the analog output. Generally, the analog output is isolated to ensure digital noise does not creep into the signal. Any ways, on the hunch it might be easier to build what doesn't work external to the SB instead of repairing it, I came across this DAC project: Go here: http://www.ezdiyaudio.com/ Find this project: Project 2: ezDAC There are even pictures using the SB as a source. ...have fun _______________________________________________ discuss mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/discuss
