UPDATE:
I bought a new cable and unfortunately it hasn't solve the problem, this noise is driving me crazy .. i am starting to think there is something wrong with the entry socket it self,
I also thought about the option that the position of the power socket and since my power cable is not right angled its causing stress on the socket and some kind of faulty connection, but I doubt it since even when I hold the cable upwards my self it comes back after a while.
what do you guys say?
I added a sample of the sound for you to hear, just ignored the fan background noise..

If i gently touch the tube it stops or weakens and after a while it come backs again..
The volume does not effect the sound.
It only noticeable when music is not playing other wise its to quiet but still annoying, is it just a normal tube hum?
