Accuphase E600 voltage conversion

I have posted a photo of the back of the PCB on 'my system' page.

I also took a photo of the wires and their orientation from the transformer.  The three wires from one side of the transformer feed to the white plug.  The four wires from the other side of the transformer feed the blue plug.  

I am confortable using DMM on the mains voltage.

Thanks

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.
