Hiya all, I bought the Onkyo HTiB HTS-760 late August last year and have been pretty happy with it. My only problem is that my work is relocating me to Sydney, Australia. Taking a look around, it seems that electronic goods in Aus. are generally pricier than in the US and I'm reluctant to sell off my HTiB for a loss only to buy a more expensive one there (for the same quality). So I thought of moving mine. Now, the only issue is that Onkyo was very specific in that my subwoofer and receiver both require 120V at 60Hz. It could very well be that they do require the 60Hz, or it could be that Onkyo just didn't want gray market sales to eat up their legitimate sales in Australia. That being said, when I was searching through Google I found a page on Yamaha's website--but since this is my first post, I can't post URLs so I'll try to describe the location here: Three "w" followed by yamaha dot com and then forward-slash yec forward-slash customer forward-slash faqs forward-slash general forward-slash faq20b.htm. The relevant part is: The transformer you are going to need is a 2 to 1 step-down type, converting the voltage from 220-240VAC to 110-120VAC. Do not be concerned about the frequency, as all of our products use DC motors, and are not tied to the AC line for speed regulation That being said, how can I tell if my Onkyo products will survive the transition to 240/50 environment? Thanks all!
