Crackling sound from speaker due to 6SN7 tubes. Overall the sound of my Chardonnay(60hrs)is very nice except for the occational crackling sound I hear on the speaker. I have narrowed down the problem to the 6SN7 tubes.
With the stock EH 6SN7 tubes the crackling is constant even when swoping the tubes. The crackling follows the tube
With a pair of 6SN7 Mullards the sound is distincly better but the occational crackle does still exsist.
The crackle at any given time occurs only on one speaker
Also, when I tap the amp chassis with my finger(not the power section) I hear the tap (amplified)from the speaker...is this a grounding issue?
Your input is much appreciated.
