Radios with vibrators run on AC from the vibrator which is its purpose and, as Howard said, only the filaments use the 6v which, like a lightbulb, also have no polarity. It seems to me (perhaps an over-simplification) that to convert one for 12v use would as simple as changing to a 12v vibrator and finding equivalent tubes with 12v filaments. I'm sure there is more to it than that, though.
