I did the upgrade in 1992 or 1993 and didn't take notes, so I don't recall the details of the job. I'm pretty sure that I used the AD827JN, which is the 8-pin plastic DIP package. The parametrics on the standard-grade device were more than good enough for the application, so I didn't see any need to spend more money on the commercial or military temperature grade or the ceramic DIP package. This many years after the job, I can't tell you which caps got changed out.
