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.

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.
hii all of the arc ref 3
can bee connvert from 120v to 220v 240v
i have done that to my ref3
Hello Simsim ,looking at the schematics of my REF 3 ( 230V european version ) I noticed three xformers , one for the highvoltage 400V , one for the logicvoltage 5 V and a 12V for the display.Can 't see extra windings for another voltage , so I think it is not easy without outboard converter to use your amp.for 230 V.I 'm very sorry for you
You can not convert the primary transformer windings to 220Vac on newer ARC products. This was done to protect their European Distributors. I also doubt they would sell you a replacement 220Vac primary transformer but anything is possible. If you are moving to a 220V area you may wish to consider selling your preamp in the states and buying a used one when you move to your new location.
