Voltage conversion of Accuphase E-650

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.

This works as well for the soft start circuit:-)

Yes, you got that right.

Congrats! Thanks for letting us know.
