Accuphase c2410

I don’t think there is any way to reduce the voltage without a transformer of some sort and is it 50 or 60 cycle.  Japan still uses both.

I have spent hours researching this in the past.  My recollection, at least on some of their integrateds, was it was surprisingly simple, though not well documented.  Involved switching some wires or jumpers inside the chassis.  I did find, but no longer have the link, persons who provided instructions with pictures. While I felt confident in my ability to perform, I was still reticent. Happy hunting, google is your friend.

Thanks for your respond. 

As you said I've been searching for long time and I found a picture which is shows 

How to convert, but unfortunately it wasn't enough information and instructions. 

I tried to find the source to get help.

Anyway I am still searching for it.

By the way I really appreciate of you good people who tried to help.

@philip4444,

Accuphase products typically feature multi-tap or dual primary windings and can be converted to 120V, 220V or 230/240V.

If you could remove the C2410 bottom cover, take some close-up photos of the power transformer primary wiring and take some voltage measurements, maybe I could figure out how to convert it from 100V to 120V.

For example, this is a image of Accuphase CX260 preamp power transformer primary wiring.

WARNING: Mains voltage is lethal

For safety reasons, if you don’t want to deal with the mains voltage, send it to an electronics repair shop and they should be able to do the voltage conversion.
