As far as I know, most of the power transformers used in audio-gear assumed to work on both 240 and 120V. Most of them have an extra output set that even no manufacturer can get rid of. Manufacturers to hide this fact from illiterate consumer can make money without extraneous part and labor investment. Madrigal in this case can be on my "Crook list" charging $150+....
I do suspect that Madrigal speculating on these piece-of-cace issues since they largely deal with Europe and less-likely will they use different transformer.
The bottom line is that if voltage is measured accross each of output windings of power transformer at the same input AC voltage they will be different in relation of 2:1(120V terminals v.s. 240V terminals. It lies in the simple ideal transformer formula:
Vin/Vout = Nin/Nout where N is the number of solenoidal winds and V is input and output voltage respectively.
If it's just a matter of re-plugging different wires from the same transformer it can only take 10...15min depending on skills of technician.
