Accuphase DP-560

Great, you’re more than welcome. Thanks to let us know, it will help other members if they need to do voltage conversion...

@imhififan ,
After I confirmed there weren't any standby transformers, I was able to change voltage to 220-240v sucessfully. Actually, as you suggested, a person who has electronic and soldering skill did convert voltage. Thank you very much again.

In this case, I want to change to 220-240v.

J1 = 100v
J2 = 120v
J3 = 220-240v 
So if you want to change input voltage to 120V, just simply move the jumper wire to J2 or move it to J3 for 220V-240V.
I didn’t see any standby transformer or J4 and J5 on the pictures, please make sure there isn’t a standby transformer hiding somewhere, otherwise the transformer will be fried when power up with 220/240V mains voltage!

if you would tell me how to solder a jumper wire. Do I need to pierce on the board before soldering a jumper wire?

Accuphase gears are expensive (to me at least), if you need to ask this question, no offense, I suggest you find someone with electronic and soldering skill to do the conversion for you.

@imhififan ,
Here are pictures of DP-560 power board:

Also, I will appreciate very much if you would tell me how to solder a jumper wire. Do I need to pierce on the board before soldering a jumper wire? In this case, I want to change to 220-240v.

@foolishman,
Can you provide picture of DP-560 power board?

imhififan, would you please tell me what kind of jumper wire I should use?

Thank you, imhififan.

do I need to change J4, too?

For 120V conversion, no need to change J4.

Thank you, imhififan. One more question, do I need to change J4, too?

You need to cut open or desolder the jumper wire on J1 and solder a jumper wire to J2.

imhififan, thank you for providing information. I will appreciate it very much if you would tell me how to change J1 to J2. Do I need to use solders?

Sorry I have no experience with DP-560, on the DP-550 Accuphase offer three input voltage selection:
Main transformer
J1 = 100v
J2 = 120v
J3 = 220-240v
Standby transformer
J4 = 100-120v
J5 = 220-240v
You can simply measure the DC resistance of the transformer tap to confirm the connections.

OP- Sorry, what does this even mean?
