The filament is not all that is oddball. The 17C9 is a dual tetrode, with a nine-pin miniature base. It has ten pins. There is a pin in the middle of the bottom. It uses a special socket with a connection in the center. There is no sub for this tube.

I have a new 17C9. I don't know offhand what the center pin is for. I think it is unique to the 6C9/17C9.
