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?
