> It's interesting to look at small Chinese manufacturers like 3Peak, Cosine, Gainsil, HGSemi, Xilluda, YW and a few others.  They all started with clones of the TL07x and 5532 but nowadays they are focusing more and more on the 5V or 12V single supply market, with several of them totally dropping 36V opamps.   Another notable point is I've never seen any OTA from any of them, even though they would be easy to clone, which tends to indicate the market for OTAs was never that large outside of audio and so cloning is left to audio specialist IC companies.

anyone of you using the NJM4565 ?
Never seen it mentioned here. Ok, it does not have JFET inputs. But +-
18V supply.
I saw that in a Peavey guitar amp from 2010 or so.
