Dear Op04,

You are sure!

From the datasheet It's the closest specs. I remembered KT315 said Russia shutdown their microcircuit factory, so I guess It's an old chip

LM741 uA741

oldest. all soviet was copied from american samples. one-in-one. nothing of own. the stealing technology, like chinese one now.
you ALWAYS can find up an analog if see soviet chip in a circuit.
