Contact Paul or Scott McGowan at PS Audio. I'm sure they have one sitting around the warehouse for a great price.

Why do you want to change frequency? Except for a few turntables, there should be no difference going up. Going down is a little tougher on the power supplies.
The Monarchy Audio regenerator can do 50Hz but is limited to between 110V and 120V and 220V and 240V in 1 and 2 volt steps, respectively. Also limited to 100W.
Pure Power and Panamax don't seem to do what you expect.
