I watched the video of the device case being opened and realized that I had wasted my money on crap again.
The chip names were removed mechanically, probably so that it would be immediately clear that it was crap).

This chip is forty years old and was used in those days for the cheapest RIAA equalizers, because in those ancient times there was nothing better.
And now this chip is very, very cheap. And it is not suitable for use with MM cartridge even at the Hi-Fi level. I don't understand who this advertisement was created for, that they chose OPAMP for two years?
They don't respect their customers... It's just ....
