Accuphase E-480

I don't have any experience on E480 voltage conversion, however, based on previous experience, brown & red wires are 100v windings, and orange & yellow are 120v windings. You need to trace the circuit to connect jumpers for orange & yellow wires and disconnect jumpers for brown & red wires.
From the picture, seem like j1, j2 & j3 are jumper for soft-start resistors circuity. Connect j2 and disconnect j1, j3 for 240v main. No change required for 100v and 120v main.

Thank you for providing information on E480 voltage conversion. I will try to do accordingly and post result.

@imhififan 
I would like to inform you that I have successfully changed voltage on E480. Thank you again.

Nice Accuphase is really nice gear.

@foolishman,
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!
