Voltage conversion of Accuphase E-650


Does anyone know how to convert voltage of Accuphase E-650 100v to 110/120v? Or does anyone provide information on voltage conversion table of Accuphase E-650?

HI, can anyone help to advice this device need to change anything, it seem like nothing i can shift here? does it work ? from 110 to 230V if turn on without changing anything?

 

 

This from E5000,  i think soft start.

as usual , if not wrong the plug need to shift for 230V, any suggestion?

 

Thanks for the analysis, do you know what kind of miniature transformer is it?

If i turn it on with higher voltage, will it burn? or the fuse will gone.

or i just simply not able to turn on?

what is see the red wire kind of link (by pass) from this board and go over to the next board which allow for the main transformer to have the voltage change.

i remove the board out.

Here what i understand, K2 input (brown) will switch to K1 (red) after relay turn on once power button press in and direct the current to sec board .

Relay is 18VDC power by transformer (from K2) thru smd Z622.

Im not sure what is z622? , i assume its rectifier to supply 18VDC to relay. or any double voltage will damage the z622?

 

 

I think the fuse is non reset-able and able to withstand till 300v. here the model i find

Littelfuse 36911000000 369 T1A 300V Fuse micro fuse Time-Lag Radial Lead Square Fuse.

The funny part is i was not able to measure any resistance after the fuse, meaning the 2 legs of the transformer, i suppose it have few milli ohms.

 

The Transformer is tiny 2VA, such of high resistance.

The brown and blue line is from same source, meaning hot wire.
