Voltage conversion of Accuphase E-650


Does anyone know how to convert voltage of Accuphase E-650 100v to 110/120v? Or does anyone provide information on voltage conversion table of Accuphase E-650?

Desolder K3, K4 and solder it to K5, K6 position will convert input voltage from 100V to 120V.
Again, I recommend use a dim bulb tester for first time power up the amplifier after voltage conversion.
Hope this helps.

@imhififan ,

As you suggested, I desoldered K3, K4 and solder it to K5, K6. Then, I used a dim bulb tester when I powered up the E-560. I can confirmed changing voltage were done successfully. Thank you very much. 
Hello @imhififan @foolishman just to be crystal clear, connector K3 needs to be moved to K5 and connector K4 moved to K6 as pictured here?

Sorry to be dense, but I want to make absolutely sure before having my tech do this.
