Below is the layout for the circuit board. I moved things around to get the film capacitors on the same copper pad as the pins of the IC as you suggested. Do you see any egregious errors? In this illustration, the copper pads are on the bottom of the board and all components and jumpers are on top of the board. +-------------------------------------------------------------------+ |Filename: layout.gif | |Download: http://forums.slimdevices.com/attachment.php?attachmentid=942| +-------------------------------------------------------------------+ -- jonheal Jon Heal says: Have a nice day! http://www.theheals.org/ ------------------------------------------------------------------------ jonheal's Profile: http://forums.slimdevices.com/member.php?userid=2133 View this thread: http://forums.slimdevices.com/showthread.php?t=20907 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
