When plugging in a new power cord (components turned off) a buzzing sound is emitted from my amp.....even if I use it on the CD player. After unplugging everything except for the amp, the buzzing still exists. Obviously the PC is defective, but what would cause this.
Follow Ups:
There is a good chance bumblebees entered the cable during its' construction.
Has there been any final word on why this sort of buzzing occurred?
Just curious about such puzzling anomalies... cause/effect and the like.
If I lived in EUROPE, you'd be right. Is there a 3rd wire independent ground standard as well as a simple 2-prong? Here we have BOTH. I can buy a 2-wire extension cord, but one blade is WIDER than the other, insuring it is ALWAYS plugged in correctly.
Here in the STATES, you CAN do a hot/neutral swap. One aftermarket cable company recently shipped 50% of a customers orders with such a swap.
Too much is never enough
Sorry but I am right regardless of where you live ;) Facts are no altered by your location.
In Europe there are typically two types of plug - two pin, no earth and two pin with earth. Most sockets have earth, but not all. Both types are compatible with each other.
The point I was making was that in Europe there is no way to reliably plug your power cord in the same way without resorting to marking it somehow.
This was in reply people who claim that you have serious problems, maybe even safety issues if you cross L and N.
You need to read my original post. No such safety claim was made or implied. I thought it possible that a H-N reverse could cause a hum or buzz, but that's all.
And being the typical tourist, when I visited Europe, I brought a couple adaptors and either devices that were 90-240v 50/60hz or used the small transformed provided WITH the adaptor kit.
I had NO issues except in Egypt where I forgot my adaptors and had to borrow huge transformer from room service in order to charge my camera batteries.
Too much is never enough
Could be pulling a lot of current (a short somewhere). I would unplug it and check the connections-something could be shoringt across the + and -.
MAYBE, just Maybe, if the cord is MISWIRED with a Hot / Neutral swap, that'd do it?
I don't know WHY, but that's all I got.
Too much is never enough
No it wouldn't. Folks in Europe who use the schuko plug have no way of knowing whether they have plugged the plug in the 'correct' way round, as you can put it in two ways. Effectively the same as a hot-neutral swap. And I can tell you that although there are subtle differences, you surely don't get hum or buzz.
All it takes is a cheap multimeter to figure it out. Surely easier than grumbling about it on a forum, no?
Unplug it, I am sure the "buzzing" will stop.
really?
Thanks

+1. After your rants you don't really deserve the collective wisdom.
