Audio Research Reference 3 voltage conversion


Anyone who knows how to convert an Audio Research Ref3 preamp from 120 volt to 220-240 volt? I know that some products needs to change the transformer and other products just needs to switch a couple of wires.

Is it possible to convert an Reference3 to 220-240 volt? I don't want to use an outboard voltage converter.

Looking forward to your responds. Thanks.

Just take it to a high end audio engineer in your country. I had an integrated amp converted to my local voltage for about $90 Euros.
Can you use a seperate wall transformer. It is a preamp, so unlike an amp the power draw shouldn't be a problem ? (note this a question).

I had the same problem, but the other way around. I drove 100 miles for what I thought would be a killer deal on an ARC preamp only to find out it was a 220V model. (then later, I wondered if I could have used a transformer or voltage regulator or something?
"high end audio engineer "

Like there are dozens listed in the phone book.
Senior, tiene mas voltages, por favor!! lolol
The problem is that some ARC products need to change the transformer (s) and some only need some wires to be switched. I'm interested to know if the Ref3 and CD7 & CD8 is the ones that need the whole transformer changed or they just need some wires to switch place.

That's important to know cause it's much more difficult and expensive to perform the transformer swap. Hope to get some answers.

Thanks.
