Voltage conversion of Accuphase A-65 or A-70

Step down transformer (versus altering the component).

Don't know if thread will help.

May be able to help you if you can post a picture(s) like others did in the above thread.

Back in the 80’s, when I sold Accuphase, they had a block inside the amp to remove and turn around 180 degrees and re-insert it to switch from 240 volts to 120 volts.  Look inside the amp where the power cord attaches. 

does it require solder?

Based on a web photo, the Accuphase A70 utilize Faston connection for voltage conversion, no soldering required.  Swapping two wires will change the incoming mains voltage from 100V to 120V. If you can post a image of the transformer 100V connection, I think we can figure it out.

How about the Accuphase A-80? I post some pictures of the power supply board for the A-80:

I will appreciate very much if you would provide information on how to convert voltage 100v to 12ov.

Thank you in advance.
