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.

I did turn it off, and on, change power cord, speaker cable it still does same thing it play for few mins, the meter start to flicking, and all sound disappear right after. any idea what may cause this issue?

I hope some one can posts images of E480 power board (front and back) so I can verify the correct jumper settings.

It’s hard to see the edges of it in the link picture from your original post. Or is there enough space to solder from the top?
