It could be for a meissner type filter design.

Dave, I think you nailed it. I have never seen that circuit before, but it was definitely s field coil design. Also interesting that the choke and field coil are in the negative side. Thanks for the info.
It keeps the entire choke at a low DC potential, and so minimizes damage in the event of a short. It filters just as well as in the hot leg.
That is common in transmitters where the voltage is several kV, but any choke should be able to handle 300-400V in an audio amp without insulation breakdown. I agree, it filters equally as well either way.
