You will need to get the specific modular jumper plugs to be changed and checked that the transformers are indeed not 110v and dual voltage. The transformers do not have specifications and just a part number so tings will get very "iffy".
Not understanding circuits and transformers, whether they are dual voltage will lead to possibly a very loud BANG instead of music from your system.
