Please excuse me if this newbie question, but if all you can find is a 230VAC to 46VAC transformer, and I chain two of them together... would that also work? I figure 230:46 = 5:1, and then 46:9.2 = 5:1... so if I feed in 230VAC into the first transformer, the output of the first (46VAC) going into the input of the second, causes output of the second to be 9.2 VAC? Is that too simplistic and for practical reasons is there a reason why this is a bad idea?
