I bought a Boogie D-180 which had been imported from the US. It came with step down transformer. I asked all sorts of people about ditching the transformer. No one wanted to know. Eventually I thought to ask my brother, the electrical engineer. He opened it, took a different tap off the transformer and it was all good. Moral of the story was find someone who actually wants the job.
I am fully aware that I am using words I do not understand on the technical front here.
