Look more closely and its not there, its a dual opamp in a sip-8 (H) if the sub is correct.

Can the OP post a picture, with a scale next to it, and clearly showing the markings?
That will help clear the confusion, the site above says SIP-11 package,

Few more info bits for uPC1186 and it's equivalents ECG1458 (this line is better than NTE).
