You just need to use a 50Hz Transformer and design it so that it will be 
able to deliver enough power when run at 60Hz. Problem solved.

So do I, but I always keep in the back of my mind that there could be a 
problem, especially if the transformer in question is loaded close to 
its specified maximum output.
