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?

Try removing and re-seating the tubes, power and small tubes. If you can identify the specific tube, and you might do this by rotating tubes from channel to channel, you can also try to tighten the contacts in the power tube sockets if the former doesn't work.
