Accuphase E600 voltage conversion

@pip555

Thanks for posting those images, for 120V mains, I believe J1 should moves to J4, J3 moves to J5. And J2 remains in the same place.

Before you move the jumper wires, please measure the following resistance and post the result to make sure if the projected configuration is correct:

Black - Brown

Black - Red

Orange - Yellow

Orange - Blue

Measurement should taken from the plugs out of the sockets.

imhififan,

Thanks for the information.  Hopefully I will have some time this weekend to test out the board.  I will post as soon as I do.  

Cheers

imhififan,

I received the following readings (all in ohms)

Black - Brown 1.3

Black - Red 1.6

Orange - Yellow 1.4

Orange - Blue 1.6

I hope that this information will help. 

Thanks

Thanks for the measurements, the readings confirm that brown and yellow are 100V windings, red and blue are 120V windings.

You can go ahead to move the jumper wire J1 to J4, J3 to J5. That will change the voltage setting from 100V to 120V.

imhififan,

Thank you very much for your assistance.  I will try to make the changes in the next day or two.  I will give you an update then. 

Cheers
