Be it 50 or 60 Hertz clocks if you do not want to alter it you need to use a DC to AC converter. Generally these things are inexpensive and used for cars or computer UPS systems. Though some of these actually have a square wave out. Not great for the little motors. Internally you would need to get into the thing that controls the 60 Hz frequency and add your control in from the Tbolt by any number of approaches. The other thing you need is a way to slew the clock forward or back to synchronize it. This is all fairly inexpensive I see APC UPS's at fleamarkets for very little cost. Especially if the batteries are dead. That would be my non HP approach to the problem. Regards Paul WB8TSL
