Yes i am new to tube, this is my first tube amp. but this ma252 amp and it's tube, both 3 months old only. noisy from both channel too.
anyway, i am going to buy 4 new tubes to test it.
I also got feedback from other ma252 owner, few of them having the same noisy when they put their ear in front of the speaker.
Thanks
