Isn't that the Sziklai or complementary Darlington?

Very poor for RF because of the Miller Effect.

Really! Some people can't spell catalog or color et. Wasn't it Webster (the
guy that wrote the dictionary) that tried to modify American grammer to
simply all those goofy old complexifications? I can just see a bunch of old
drunk Lords and Priests figuring out new and clever ways to confound the
ignorant peasants, and changing rules keep the younger generations scholars
humble and dependant. Kind of like Micro$oft with Windows. Or the government
with the tax code.
