It is not hard in any respect, but it surely does require that you have usage of a variable AC voltage of between three and 20V. A multi-tapped small energy transformer can be utilized, or use any transformer that you've helpful as well as a Variac™ (variable voltage transformer).

Overall, the procedure explained is an easy and Secure way to operate an aged synchronous clock. Even though there are other choices to the method described, they require the acquisition of areas which have been significantly costlier than the double insulated 16V plug-pack, and don't supply exactly the same General safety degree.
