Mis-understood again. I thought that by 'Near the rail' you meant that the voltages on the inputs couldn't be too near to the supply voltage. Presumably this is why +/- supplies are best for them?
I have studied the data-sheets but the required information isn't on them in a way I can understand.
I had a play with another 741 on a breadboard and that was plain weird: I'd only connected the power and a 1kΩ resistor and LED to the output and it wouldn't go out with nothing on the inputs or even with them shorted.
I'm starting to think and EM80 would be easier!
