I purchased an Ami-Rowe R90 when I lived in the USA and used it successfully on USA power. I have now bought the machine back to the UK with me. Looking at a manual I have found and also looking at the power supply it would appear that the power supply is automatically dual voltage. On this basis, I am presuming that I do not need a step down transformer to use it in the UK and the records will also play at the correct speed. Am I correct in my assumptions?
