I just kept staring at the schematic until it started to make some kind of sense. It's two common emitter amplifiers -- one PNP, one NPN -- with local shunt feedback on each. What makes it hard to see is the biasing -- they actually share bias current, which I haven't seen before. Have any of you seen this topology elsewhere?
