Sounds almost like a transconductance output stage (voltage to
current using current feedback, thus the resistors tied to the rail.)
to drive a transformer output stage. I would need the schematic.
Describe it better?

I can assume the outputs that run to the transformer(s) are tapped at
the resistor/emitters joint? if so the amplifier is still stereo and is
a transconductance design where they are most likely using current
feedback. This topology will convert the input voltage to an equal
current output. Then I can only assume that current is intended for the
final transformer outputs.

FYI. Transconductance amplifier topology is not to be confused as a
"class"
