Possible to lower voltage?

Hey guys.
Question:
Is it possible to lower the dcv, by hooking up some sort of resistor on the primary terminals of the PT?
If this is a stupid question, please bare with me...

Isn't that what your variac is doing?
Or did you mean a resistor like this?:

I don't have a variac, so I figurerd a resistor like the one in the pic would do the trick... Is that what it does?
What effect and value would I need?

You can drop global B+ with zeners too. If you google it, there are a bunch of folks with 100watters dropping specific amounts. They get hot, but so do those huge resistors. You can make that thing Neil shows variable though. It's like half an Air Brake, so..
