VT 100 MkIII and LS16 MkII, both running beautifully 2 months after conversion. The tech did say there were 2 transformers in the LS16, but they were both universal. If you think about it, it's crazy economics for a manufacturer to go to the expense of making different transformers for different markets (probably less than 50 VT100s rated at 240 volts sold in my neck of the woods) when a universal can do the job for all markets. But no manufacturer will tell you that, as their priority is to protect the market for each distributor in each country. Problem is, that where I'm from, ARC products are priced at twice the price of what you can buy them for in the US. BTW I ran both through step down transformers before converting them with no degradation in sound quality (you just have to make sure the transformer can handle the maximum wattage of the amp). I just decided to go ahead with the conversion because it was easy to do and to clean up the mess of electronics behind my rack.But that's an option if you don't want to keep the equipment original.
