If that transformer is hot, then you are probably looking for a problem with the 5VDC super regulator on the far right hand side of the board, and perhaps the DAC chip. You could try replacing the transformer first, however my guess is not a bad transformer, but something shorting out those DC rails that is causing the transformer to overheat.
You could test the transformer by temporarily removing the rectifier module on its output. I think you should see something like 12-15VAC open circuit voltage across the AC pins. If the transformer is bad just replace it - digikey has, or at least used to have them. If the transformer is OK then defeat the super reg by removing some series element - I don't know which component off the top of my head but you will be able to find general schematics for a Jung regulator. Then apply clean 5VDC from a bench supply to the labeled test point and see if the DAC works. I have never heard of this problem before so I'm just giving you some things to try. Where to go next depends on what you find. -- seanadams ------------------------------------------------------------------------ seanadams's Profile: http://forums.slimdevices.com/member.php?userid=3 View this thread: http://forums.slimdevices.com/showthread.php?t=81822 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/audiophiles
