Is this normal for these amps? This is my first tubeamp and this noise is killing me. I thought faulty preamp tubes caused this noise, because 3 out of 4 were leaking. Then i threw new preamp tubes in and the noise is still present. i have tung-sol 12Ax7 in v1 and rest of them are jj ecc83 tubes. i have nothing in the fx loop and speaker cable is fairly new orange.

Doesnt matter if guitar plug is in or out.

Oh and this is pre infinium if it matters.

ps. English isnt my first language, sorry about that.
