Apparently they are rather valuable now.

The earliest
I have seen so far is a
Sherwood FM tuner ca. 1977 that uses an RCA 1802 (e.g.

Bit of trivia. That tuner was designed and built in Milwaukee by a
company that a friend of mine worked for. At the time, several of
his friends built units up from leftovers from the production run. Patent says Grafton (northern suburb). PDF manual,
including block diagram:

Interesting to see, although it was 11 years ago I worked on them.
I RE'd the schematic for half of it if needed. It was interesting to see the
1802 with all it's support in there when I first opened them up.
