Default American 60Hz clock - Will it run on pulsed DC?

Hi all,

Excuse me if I'm being ignorant here but I wanted your collective opinion, first I'll set the situation...

I am currently looking at an american clock radio for somebody, it's made by Commodore and is a 117v valve set, now the 117v part isn't difficult as I have a suitable transformer that will fit inside the set as there is lots of room, the issue I do have though is with the clock itself as it runs way too slow on 50Hz
Now, my question is this.. If I pulsed DC into the clock winding (also designed for 117vac) at 60Hz would it work? and secondly and most importantly could I do it with a much lower voltage?

Answers on a postcard please!!
