ARC Ref 3 and ARC Ref 110 tubes

I have a ARC Ref 3 and Ref 110. I am getting a crackling sound out of the left speaker. I am assuming I got a bad tube somewhere. I tried replacing the Power tube (6550C) in the Ref 3 but I still get the crackling sound out of the left speaker. I got 1500 hours on the other tubes in the Ref 3 and 1000 hours on the tubes in the Ref 110. Is there a way to narrow down which tube might be bad without playing a chess game of swithing tubes all around? It seems to me my system has also some slam loss.

Can someone tell me after how many hours on my amp that I need to be concerned about the bias? What is it all about anyways? Thanks

Yeah, that's right I do. I also drive a car, but do I need to know how everything under the hood works? NO! I have a stereo system that I enjoy listening to. I don't feel I need to know every nuance of how it works. This is a forum to help each gain knowledge, not criticize.

Mofimadness can you explain the idea a little more. Sorry, but I don't get it yet?
