Your question assumes the existence of a "right way". For a dual supply (positive and negative), one might envision getting a small improvement in measured hum by swapping the primary leads. But if this is so, then it's likely the result of asymmetrical capacitive coupling between the primary and the two secondaries. The relationship there is likely not going to be repeatable from one transformer sample to the next, and certainly has nothing to do with transformer dots. See figure 3 on this page: http://www.dself.dsl.pipex.com/ampins/groundloops/grndloop.htm#cap But I haven't seen anyone provide evidence of improved audio performance from doing this - only anecdotal "evidence". -- andy_c ------------------------------------------------------------------------ andy_c's Profile: http://forums.slimdevices.com/member.php?userid=3128 View this thread: http://forums.slimdevices.com/showthread.php?t=36626 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
