Help fix my JVC AX-2 - Super A IC VC5022

Hello,

I have a JVC AX-2 with problems on the VC5022 IC, but it doesn't seem to work, I inverted the IC channels and it worked perfectly. I did a lot of research and I couldn't find the original IC for sale, there are only fake or defective ones on the market. Does anyone have a schematic of this IC to build a PCB to replace the IC?

I don't have much knowledge in electronics, but I believe I can build a PCB, I just can't find any schematics with the components.

thanks to anyone who can contribute!
