Discussion about the Korg PolySix synthesizer

I have never seen an old production KLM366/KLM396 before, but there is no
"old production" KLM367A, so they must be the same in both machines. The
clone is exactly the same, so it should work just like the original.
According to the schematic diagram, IC9 is a TL072 and IC1 is 74LS04. It
looks like IC3 is the CD4011.

You do not have an idea for my problem ?
The equivalent for IC9 is TL072 and IC1 is a CD4011 (CMOS NAND GATES)?

) the IC1 and IC9 is physically poor (no text, and pin is black). How to
test this IC ?
