Seth, we just discussed and presented roughly 3 main methods of driving any tube
into Class B2, but in particular the 811
without a transformer?
No transformer is ever needed for AB1, as it is cap coupled.

PS. Getting "300 watts" out of a pair of 811s, even given the 1250vdc B+ is a tad
optimistic, imho. Maybe
peak??. But don't try a sinewave at that power level.
Of course back then 811s were easy to find, and cheap. WWII surplus...
