Accuphase E-480

Does anyone know how to convert voltage of Accuphase E-480 from 100v to 110-120v? Here's a picture of the power selection board for Accuphase E-480.

E-480 isn't like E-650 and E-800. E480 has jumpers of J1, J2, J3, J4, J5 and J6 instead.

Thank you for providing information on E480 voltage conversion. I will try to do accordingly and post result.
I would like to inform you that I have successfully changed voltage on E480. Thank you again.
Congratulations! Please let us know the jumper settings for 120V, maybe a close up picture will be nice, it will help other members if they need to do voltage conversion. Thank you in advance!
Thank you!!

Here's the jumper setting changed for 120v:

J4 -> J5

J10 -> J8

J6 -> J11

Thank you again.
