Good Morning Mark,
You should examine the transformer that's in there for higher voltage taps: they actually could be there. What you run into is manufacturers have to pay a fee to the safety agencies of every country they sell the machine in, so if for example this is a Japanese spec machine it will not include the North American (115V) safety agencies or European (230V) ones, even if the transformer actually is equipped for them.
Why pay a fee you don't benefit from? (What does a Japanese customer care if the thing won't catch fire in Canada?)
May not work out, but it costs nothing to look!
An old employer of mine actually let the safety agencies lapse on an old product of ours because at the volume they were selling it was eating the profit, and the existing customers certified at the system level so they didn't care.

Hi Steve it sounds as if its a 100 volt fixed one without soldering to other prongs for different voltage so will need a transformer form a beat up UK or EU machine with the 240 option 600 machine.
I`ve never heard of a transformer going so will be many sat in cupboards etc hopefully in old ramshackle machines. Fingers crossed.

I've been working in power conversion for more than 35 years and have never seen a power transformer die that wasn't killed by something else!
-agreed: all the machines with dead motors, dead sound, worn guides, broken claws, worn and cracked gears and every other evil that befall these, odds are every one represents a good transformer.
It's kind of a shame it worked out this way for you. My North American spec ELMOs have 115V ONLY on the ratings plate, but the transformers are tapped for basically everywhere on Earth!

Steve - that's very interesting information that I've never heard before. Have you by any chance come across any other make of projector sold in the USA that this applies to?

I have a Eumig 800 series that is rated 117V only, but I'm pretty sure that's configurable. My son has a Yelco silent machine with the full spread of voltage ratings...but no safety agencies! (That's frightening!)
I could see this applying to a great many devices, especially from way back when. It was probably cheaper to have a "universal" transformer with multiple taps than buy smaller lots of six different ones, but by the same token six different ratings plates is no big deal!
-especially since doing that might reduce five different safety agency fees per unit to only one!
It's a little different now. Many modern devices use universal input supplies: you can plug 50 or 60 Hz, all the way from 90 to 264 VAC in and they will regulate at the same output without changing anything inside.
My laptop charger has safety agencies for all over the place.
Then again, all I have to do is swap the plug or get an adapter and I can use it anywhere.

Steve, I recognize you're professionalism of course I do, but Please don't insult anyone's intelligence here when something clearly has has been caned the arse out of, for the sake of pursuing someones pipedream!

Hi Mark,
It`s too bad that you will have to hunt for a new transformer.
I have several ST-180 part machines obtained in Japan and all of them have 125V transformers. Even though they were made for the Japanese market(100V) there is a cable that can be moved(with no soldering) from P1 to P2 on the board attached to the transformer. This allows them to be used in the US or Japanese market.
I realize though with you being on 230 to 240V though that probably does not help you at all.
