Yes, a "Matrix" amp. A+B from the push-pull transformer, A-B from the smaller SE transformer, and those outputs are added and subtracted to get channel A and B to the speakers.
Would work in a small phonograph, with cartridge outputs wired out-of-phase. And of course, there are no other inputs. There's one of these at the AWA museum (recent donation) - I can see if there's a manual for it.
