Is there a grid resistor connected to ground in addition to the IT connected to the bias supply?
I'm just trying to figure out why there would be 1ma of DC current flowing.
There shouldn't be any.

No grid was harmed in this experiment. Output was connected to secondary of IT I intend to use in a yet to be constructed amp. What I did initially was connect the negative output to one end of the winding and the positive end of the supply to the other of the winding. I then attached the meter one lead to each end of the winding. This is what gave me -0.4 volts. After my first post I connected one end of the winding to the negative output and the other to the red lead of the meter and the black lead of the meter connected to the positive ground of the supply. I was able to adjust this to the -32 volts I wanted. Hope this clarifies things.
