Voltage conversion of Accuphase E-650

@systemroot 

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.

works as expected:-)

works as expected:-)

Good job! @systemroot👍, thanks for sharing!

BTW, have you figured out what J4, J5 and J6 for?

@imhififan good question with J4, J5 and J6.

I recognized you have mention something similar for the E600 above in context of soft start resistor settings. Any idea if I have to change these jumpers, too?

I think it makes sense to remove J5 and J6 but add J4.

Then there is the maximimum resitor value set.

I have manual of ps510 and there is also a kind of soft start circuit like this.
