Yes Andy, they did. I have many of them from the K155, and K134 series (logical), and I have used them to build my digital clocks. The Selena B216 has an audio output amplifier IC which is an equivalent of the TBA-810 chip. My first automatic fridge protector used a Soviet equivalent of the 555 chip
My parents bought a Radiotehnika 301M record player in the 80s. We didn't have R2R or cassette player but we did have several records and I played it a lot. I want to restore it someday. Not sure if it was considered HI-FI, but it sounded very well. This record player uses an IC as the front end pre-amplifier
