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?

If following the voltage conversion table to 120v from the e-260 service manual, and apply the rewiring on the e-270, it turns out that pin 2 should be black and pin 4 should be orange.

@jgore 

Pins 2 and 4 are not connected to any part of the circuit, they are there to house unused wires. So it doesn’t matter if the black and orange wires are on pin 2 or pin 4.

Connect the yellow and brown wires to pin 3 to set the voltage to 120V.

Hope this helps.

Thanks so much @imhififan 

does it matter which wires go on top and on the bottom of pin 3 ? 
also, is it possible to use my synergistic research purple fuse on the e-270 ? 
the fuse is currently used on a 120b Hegel H190 and it’s rated at 10AT ( slow blow)

Thanks again for your support

IIRC, the fuse in the E-270 is 5A slow blow, your 10A SR fuse will not provide desired protection.

 

Hello @imhififan,

Hope this message finds you well. I am a young lad from France and love vintage Hifi gear. In 15 days, I will be visiting Japan and would like to buy an Accuphase E303. Do you think that the wiring system is similar and that it would be possible to convert it to 230V AC ? Below, you can find some of the pictures that I found on Internet. 

 

Thank you very much for your answer and for sharing your knowledge with all the forum members 🙏🏽

 

Best regards,

P.S. If you know these devices, which one do you prefer? E202 vs E303? Do you think they can marry well with a pair of Ditton 66? I have currently a Citation 16+17 and I am not happy with the result. Thank you
