I live in the US and after twenty years here, I am planning to move my family back to Australia (kids born in US) as I am retiring. My issue seems to be through going through the different boards on pinball machines is that they are voltage (and maybe more so frequency but please correct me if I am wrong) dependent on the country of purchase. Because I am not moving until at least two years, I was planning to buy a couple of machines now to enjoy with the kids and take them with me to Australia. I believe using a stepdown transformer will not work as the frequency in Oz is 50hz while the US is 60hz. Would there be anyway to have a shop in Oz flush out the old settings and install new ( remember I don't know if it is software controlled) setting or would I just need to hold off and buy in Australia. Any help understanding how region settings works. Thanks.
