AC Adaptor makes BUZZ noises!

[Shitface]

When i plug my AC adaptor in to the wall, weather its connected to my sega cd or genesis, it makes a buzzing noise! Why does it do that. Is it safe to use still cause i am affraid of something blowing up.

The AC adaptor of my MegaDrive does not make any noise but the one of my megacd 2 makes a very low buzzing noise.

I do not know if it is dangerous or not. I have been using it for almost ten years without problems but you never know...

Thats normal.

All adaptators are made with a rotative 'fil" so this creates oscillators which can create vibrations with the plastic case.

And the noise come from that.

Just try to hurt a bit the plastic case to remove eventual vibration sources.
