AC Hum problem
Sun Apr 6 00:24:48 EDT 2008
Are you sure that none of the two-prong ac plugs on any relevant piece
of equipment have been reversed since your last successful use of the
system? If there are any ac cords that you can plug in either way and
that you occasionally plug and unplug, the plug polarity is a likely
cuprit. And, in fact, is it possible to reverse the polarity of the
patch cord itself? If so, try reversing it--one end at a time.
