New Ground Loop - What Could Have Caused?


I never before had a ground loop in my BR system. Everything, amp, pre, tuner, including Verizon FIOS box and TV, is plugged into a PS Audio Juice Bar, which is plugged into an Audience AR1P plugged into the wall.

Upon returning from vacation, I now find I have a very nasty ground loop I so far have been unable to cure.

What would cause a ground loop when there had never been one before? Thx.

This sounds like the neutral wire that is also tied to the ground was no longer making a good connection. The bad connection could have been in your main breaker panel, meter box, or utility line feeding it. Without this connection, your outlets could have 240 volts coming from some of your 120 volt outlets, down to zero volts from the other outlets, do to a bad neutral connection. A lot of the time, anything that draws a low amount of watts, will usually get the higher voltage, and burn out. That neutral wire keeps one phase (hot) line at 120 volts, and also the the other phase (hot) line at a 120 volts, each half of the 240 volt line. It's good to hear everything is fixed, and no major loss.
good to hear that you got it fixed, Neal. Is it safe to assume that ATT is picking up the cost of the electrician?
