Accuphase E-3000 voltage conversion

Actually I have to correct myself. After looking at the traces on the solder side I currently think J1 needs to be set along with either J5 or J6 (one of those should be for 220V the other 240V). Would that make sense? 

Here’s another shot of the PCB:

As for the auxiliary transformer. It should be on the two photos above. I’ll have to take apart the side panel to access it completely, however on first glance I did not see any jumpers or other means for switching voltage settings.

Thank you for the photos. Here are my findings:

100V setting = J2, J3, J6

120V setting = J1, J4, J6

220V setting = J3, J5

240V setting = J4, J5

Regarding the auxiliary transformer: if the unit is configured for 220V/240V, you must replace the transformer with one rated for 220V/240V. If configured for 120V, you may connect a fusible resistor in series with the primary winding of the auxiliary transformer to step the voltage down to 100V.

Best regards,

@imhififan Thank you so much for the illustration, of course that makes more sense setting J4/J5. I really appreciate your help. 
regarding the aux transformer, I took it out to get a clearer view. Indeed I would be running the system at 240V. Attached you can see more detailed shots of the top and bottom side.

This thread is interesting. Daniel1115, can you take a picture of what your unit looks like opened up and disassembled to get to the power supply?

@easystreamer  Sure, I’ll take some photos of the unit. Getting to the power supply PCB is very simple, just open up the bottom panel and it’s right in front of you. Getting to the auxiliary transformer requires a bit more disassembly work: Take off the side panel and move some of the cable bundles. Taking off the side panel will make it much easier to access the aux PCB. 
The current challenge that I’m having is finding a matching part for the aux transformer running on 230V and exactly fitting the PCB. 
I contacted the manufacturer of the original part asking if they sell a 230V part, yet to receive a response though.
