I am not sure but as many tube radios do, this one has low ohm resistors connecting Neg to the chassis, creating some negative biases (wherever they might go).
Now, they rely on the consumed current to create the bis and is a bit imprecise. In this case they created the exact divider, so the voltage is less dependent on the current (still dependent though but to a lesser degree).
