Thanks STJ. I found an equivalency sheet that gave the NTE and a few others. I found their datasheets just can't find the NEC datasheet. I've got a schematic that gives the pinout for the NEC but just want to be sure by finding the NEC datasheet. The board has 4 pins in a row like the rectangular op amps and I was thinking maybe I could just put a socket in and could then use more modern op amps in the unit. Out of eight I have, I've found two bad already. So I was thinking that's a pretty high failure rate.

old op-amps did fail a lot.

for the nec, you may need to look for a pdf of an old nec databook rather than a datasheet.
datasheets did not really exist before the net.

I think a place called IC37.com has a datasheet for it. Too bad I can't read Japanese. It looks like they want 15 Yen for it which is what, maybe a dime. Too bad for me.
