Still some time I have a strange noise like a spring noise with the ef86 channel, very slightly when I don't play.
I look some videos on youtube about microphonic tube and I heard the same noise on one of them!
Is it dangerous for the amp? Because it's not very deranging?
Artisan 15, EF86 microphonic ?

In fact, I made a test and it's one of the sovtek ECC83 which has a problem!
