Maybe you can flip/flop the left and right tubes and see if the problem travles...This will tell you for sure..I does sound like a bad tube though..
Slight "Crackling" noise in right channel of amp
Hello - I just picked up a Musical Fidelity KW500 integrated and it's sounds amazing. However, when I stopped playing the music, I noticed that with the volume dial at about 50% and no source playing, there is a crackle noise that comes from the right speaker. It's not extremely loud, but it's loud enough that I can barely hear the 'crackling' from my listening position (7' away) if I listen for it. The other channel has noise if I get up close, but it's constant and smooth...like it should be.
I have swapped cables and replaced cables to confirm that it is definitely the amp channel that is the culprit, and not the speaker.
Now, the music sounded amazing, but because of this, I can't help but think that this is taking away from it somehow and that it could sound even better.
Does anyone have any idea what might be the cause of this unwanted noise? I plan to call Musical Fidelity on Monday but I'm just fishing for thoughts/ideas in the meantime.
Any feedback would be greatly appreciated.
