    Hello, I need information about the integrated circuit "MN6520", used in the sub-tone boards.
    Some commercial replacement or where to buy it?
    It's to make some sub-tone plates that I need.
    I can not find the integrated circuit for sale, nor in China.
    And I do not know if there is a compatible replacement that is sold in stores.
    Thank you
