Yes, remember that it's perfectly OK to run a 120V load between one side 
of the TX primary and its center tap. This is often done by the first 
rate amp mfrs. And remember that it is NOT OK (and is illegal) to run a 
120V load between one side of the line and ground. Indeed, putting load 
current on ground is a recipe for hum pickup. And bonding neutral to 
ground is even worse.
