Nothing special.
Transformer coupled SS-PP amplifier with transformer output.
Was common in the 60's...

No, it is not a PP amp.

It reads Single Ended, you mean that is not PP ?

Ah, i sees clear now : it's got a 2.4V dynamic CCS on top, a transformer coupled input for the bottom driver stage, even a lytic on the crossroads to block DC to the output trannie.
Let's give Steve Eddy a call to be sure.

if you look at the input trannie phasing and the way the output transistors are connected, yes it is a P-P (push pull doesn't have to have the output transformer in the collector circuits to be push-pull. most solid state amps are push-pull). if it were single ended, the top transistor would not be driven by the input trannie, it would be a current source.
