Accuphase E-260 Voltage Conversion (100V to 230V)


Hello Forum Members,

I have an Accuphase E-260 Int. Amplifier wired for 100V wall outlets. I am trying to convert it to 230V. From various threads on this forum, I could figure out that this unit has quick connect terminals for winding wires. It was less daunting to find that out!
Can somebody pls help with it's 230V wiring diagram?

imhififan,

This is so helpful. many of us on this forum have reasons to thank you. I am gonna make these changes and report back if it worked. Do you also suggest changing the fuse and amplifier power cable to meet new current requirements? I am not able to locate the fuse though.

Regards,
Abhishek

Yes, for safety reason, changing the main fuse is a must!
Usually you can find the fuse on the power switch pcb or soft-start board in a Accuphase integrated, and its clearly specified the fuse rating requirements on the board.
For power cable, you can either buy a new cable or some kind of plug adapter, I always found Accuphase cable are good enough for my use.

Before you swiping the wires, measure the resistance across tap 2 and tap 4, after conversion the value should be about 4 times higher.

I also strongly recommend to use a 230V 100 watts Incandescent light bulb in series to power up the amp at the first time after voltage conversion.
If anything goes wrong the light bulb will simply light up instead of dimming and save the amplifier from any damage.
I can confirm the given wiring diagram works for 100v and 230v for E-260. I changed mine to 230v. I must note that the system required some 20-30hrs of burn-in after the change.
Thank you @imhifiman

Hello imhififan,

I got an Accuphase E-270, I also want to covert the voltage, here is the picture

 

Would you know it the same as E-260 setting and just change the new cable color? Thanks.
