As it says - for those running a 2:50:2 do you run Class A for 50W and the most pure sound, or Class A/B for the higher headroom of 62W but maybe a little more colour?
 
For tube life, it's better to run A/B mode 'cause in Class A mode, it's running full throttle for lack of a technical term so you'll burnout the tubes faster. Class A mode feels more compressed than A/B. But it really depends on what you like.
I usually run JJ E34L's on one side Class A/B and JJ 6L6's or JJ KT77's on the other channel, sometimes in Class A or A/B. I like that tube combo very much!
