Anyone use the Russian Equivalent of SO42P Mixer IC's?

I ordered some but do not need them just yet. They are for repair purposes down the road. I have had great luck with Russian Mil Surp tubes, diodes, resistors, air variables, ceramic high voltage rotary switches and teflon cap's.

I am sure I in a pinch I could sub the SO42P in for the TDA6130-5 but since i have never done that I...
