Popping noises

I noticed today a very slight 'popping' sound in my left channel. Noticed this noise while my tube amp was idling and I am presuming it is a driver tube in the amp section...is this a fair guess or could it be something else?

I will re-check the bias, although on my ARC amp this is a real chore...:0( The driver tubes, as well as the power tubes, are all fairly new with less than 50 hours on all of them. What I am wandering is if my JJ driver tubes are going noisy? JJ's seem to be infamous for this problem although I do like the sound of these.

Today, I checked the bias and re-seated all the tubes. The bias was fine and there were no more popping sounds-- the amp sounded absolutely beautiful again..:0) After a couple of hours listening, I know again why I just LOVE this amp.
