Voltage conversion 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. 

Glad it done successfully ... thanks for letting us know.

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.
