Stevens" My cross-reference charts say that the TI OPA704PA (in current production and available from Digi-Key) is a drop-in substitute. The Philips ECG944M may also work.

The CN in plastic 8-pin DIP, 0C to +70C. According to the NS book, the H is metal can, -55C to +125C. Can throw a couple in the mail from Vancouver, Canada, if you don't find anything faster/closer. What's the app?, does it really have special requirements? So many op-amp types have been produced over the years. Perhaps I exagerrate, but they seem like transistors in that a dozen modern types could cover substitution for the entire range of types.
