one of my WE91 knockoffs runs 300b pretty easy, with a 5u4 rectifier, I am running 310 v A-K at 60ma (18.6w diss), it sounds very good, but then when I A-B it with another amp running up around 28w dissipation, I really cant hear any significant difference. What may occur, and I am guessing, is the amp running at the lower dissipation may sound the same for a longer period of time than the one running the tubes harder. Even the one running the 300b at 28 watts is still only running the tube at 75% of the original spec, and 70% of spec for later tubes.
