Hardware Dorkery / DIY tube preamplifier kit

Everything elce I can work with, but how could I deal with the fact it's looking for 250v and likley at 50hz not 60hz? A step up transformer would be large, heavy and generate alot of heat...that and it would be un-efficient. Maybie I need to find another kit with a different design, but one like that would work well when put into a nice case of some sort. I'd really like to build one, just to say I have and to see how it sounds with my setup.
