I looked over at Digikey, I have an account of course. They don't want but like 20.00 for three shipped cut tape so I figured I will buy them and compare them physically to the ones from Ali. Just see. As you all said with a little more reading and research I see these are Brown Burr chips, Texas Instruments. They are manufactured in USA not in China. They never made them at all in China so getting them from there they are almost definitely fugazi. Anyhow, I will have the adapters from those and if they are acceptable I can use them with the Digikey op amps if I decide to do it. Thank you guys for alerting me to this. Fact is I figured everything, I mean just about everything electronic was made in China anymore so I never even considered that the op amps may be fake. Live and learn.
