Kevin: Yes, zero ohms from the center tap to any other chassis ground. And (this is something I don't understand) zero ohms from antenna post to ground when the rheostat is at the lowest setting. When the rheostat is turned (440 ohm element), the antenna-ground resistance goes up to about 100 ohms, then back to zero at the highest volume setting.
Tom: Makes sense. I also think it might have facilitated placing the transformer into its chamber. It's a tight fit with very little room for fingers. I have to use a pair of pliers on the core to pull it out.
