Why are you using such an antique part? Anyways, check this link.

I always do forget to check stickies. Its just what the schematic called for, Im using it for a non inverting summing amplifier. Is there a better op amp for this?

How can I adapt one of those to this circuit?

Just about any opamp will work in that simple circuit. They need a negative supply for their output to go down to 0V.

An MC33171 or MC34071 opamp or one opamp from an LM358 or LM324 will work if its negative supply terminal is connected to 0V and it has a load resistor to 0V. Then a negative supply is not needed..

If we use IC LM338 and IC LM107 normal IC LM338 have current about 5A then must use 2 pcs. Make enhance current get be 10A besides. Please try to experiment.
