Sumo input voltage question - US/UK

I am the original owner of a Sumo Andromeda Class AB amplifier and Sumo Electra-Plus Preamp and I will be moving overseas to live in the UK. I am assuming these items will not work in the UK due to 230v/50hz vs. US 120v/60Hz differences. That being said, I notice on the original boxes that there are check boxes for different versions depending on which country Sumo was shipping to so they boxes are labeled with these options and checked appropriately. Does anyone know - if by chance - the actual transformers used in this amp and preamp may have the capability to be "jumpered" so they will work to support different different input voltages and frequencies? I think there may be a slim chance, so figured I would ask. I know some of my NAD equipment would work in either country, with making such changes and changing out the power lead, of course. Thanks for any information you may have.

If they are marked for different countries on the box a good chance is they have multi tapped transformer primary windings & if you are lucky they might be marked for each one inside the unit.If not marked, any electronic repair shop would be able to swap the winding to the correct terminal for you & shouldn't be too exy.

If they don't have multi tapped windings you can buy a step down transformer for each unit (cost of these varies with the current needed for each unit-the pre amp wont draw much but the amp might ).
