Is my Ecc83 dying ?

  1. Nik74
    i know you re not supposed to touch tubes while they re on but there you go I did... I wanted to see how hot they would feel while I was listening to my headphones. To my surprise as soon as I very gently tapped the tip of the ECC83 a rather prominent cracking sound was heard from the right didn’t feel that hot so I gently touched again and the same thing happened, the noise wasn’t subtle , in fact it was quite loud. I sometimes hear a slight crackling sound through the right which I thought could be rf interference but now I m worried the tube might be on its last days. The 6SN7 are completely silent.
    Do you guys have any advice, input or idea on this ?
    Help would be much appreciated, thanks
