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?

Just confirming that for the E-470, switching the voltage from 100V to 120V requires only moving the connectors from K3 to K5 and K4 to K6, with no change to the jumpers J1 and J3.

Yes, switch the voltage from 100V to 120V, leave jumpers J1 and J3 unchanged.

 

Thanks for confirming. Do you tweak the bias after doing a voltage conversion?

While it is not necessary to bias the power amplifier after voltage conversion, I thought it would be a good idea to record the rail and bias voltages before conversion for future reference.
