It's a simple circuit, on the secondary of a transformer. Remove the primary current, and you'll find no DC remainder. The only effect that I can see, is more current in one half or the other of the cycle. Given that each individual load is small, and the fact that any large number of them will average twoard a 50/50 distribution of polarity, I don't see any problems. This sounds like the sort of troubles you get into when you chrome-plate your roll center. -- Dave's Engineering Page: http://www.dvanhorn.org I would have a link to http://www.findu.com/cgi-bin/find.cgi?KC6ETE-9 here in my signature line, but due to the inability of sysadmins at TELOCITY to differentiate a signature line from the text of an email, I am forbidden to have it. -- http://www.piclist.com hint: The list server can filter out subtopics (like ads or off topics) for you.
