Voltage conversion of Accuphase E-650

Yes, Fill the empty holes in K3 and K4, it will increase the mechanical strength of the PCB especially holes with through hole plating. 

Hope this helps

@imhififan Many thanks!!!

HIi @imhififan,

you are a specialist as I understood:-)

I want to switch my Dp900 & DC901 from 100v to 230v. Any idea if thats already discussed here in an other post? Or do you have an explanation already?

In the older models it was much easier to do as it was described more or less in the device itself...

Thanks in advance.

Thanks! I'm just a HiFi hobbyist, Not a specialist at all🙂!

Sorry I don't have any experience for voltage conversion of Dp900 or DC901. However, some Accuphase CD player utilize low power transformer with jumper setting, J1 for 100V, J2 for 120V and J3 for 220-240V, IIRC.

If you can post a picture of the power board, perhaps we can figure out how to convert the voltage.

Hi @imhififan

hope it works with the pics:

My guessing:

DP900: just change the two black wires with the two brown wires.

DC901: As you said only change the jumper from J1 to J3

What do you think man:-)

I have manual of the DP800/DC801 looks bit similar.
