You're exactly right. The only practical advantage using the direct coupled 6SN7 is overload recovery. It does not have the current capability to establish realistic A2 operation. Regarding anode dissipation, I run all my NOS 211s (mostly GE) between 70W and 80W. The latter is the limit of my OPTs at 1KV. 80W seems to have no detrimental effect on the tubes (but 100W might). :)
