Is there an easy way to fully test an op-amp. I have mostly 2 channel TI op-amps ( most of them are obsolete 5534's). There are about 40 of them in each channel of my 40 channel mixing console and need to test them since purchasing 1,600 op-amps is far too costly for me. I searched for op-amp testers and came up empty, however, I did find many op-amp tester circuits online. The few I built did not work and even if it did would only tell me if it was working, not how well it was working. I would very much appreciate some help in finding a way to test these op-amps.
Thanks
Jeremy
