I have one of those cheap 0-30V 3A power supply kits that are known to blow TL081 op-amps, so I want a circuit to plug them in and test them.
I tried this one where a LED blinks if it’s good, but nothing happens.
My circuit - my SCH has pin 2 and 3 flipped.

I did this test and 4V in makes out 7.3V with pin3 at 5V, which makes pin 2 read 5V.
Is this last test good enough for a blown op-amp if the voltages are the same as in the vid, because the 3 op-amp pass this test.
