Wright 2a3 SE monoblocks..

Can anybody tell me whether this amplifier was released in the USA/CANADA with a universal power transformer (120/240 with optional taps)?
I would think you would be able to see if there are other taps on the primary of the power transformer not being used.
I have 240v(uk) Wright 2a3 SE monoblocks and I know George (RiP) used Sowter Trannies to get the 240v input....so it seams unlikely that they were usually 120/240v

Fantastic Amps by the way.......
