Voltage conversion of Accuphase A-65 or A-70

@imhififan 

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.

@imhififan 

Thank you very much for the information you provided. I will try to do accordingly. I will keep you updated.

Thank you very much again.

@imhififan 

Thank you very much for additional comments. I will surely use DBT after conversion. 

@imhififan 

I have successfully converted the A-80 from 100v to 120v thanks to your great help. Thank you very much again.

Meanwhile, do you know information on voltage conversion of Accuphase control amplifiers like C-3900, C-2900 and C-2300?

Thank you again.
