...and first questions, if anyone has some general tips...
1. the Schaffner is riveted (?) to the frame, at two points. I don't need to rivet in the Delta 06geeg3e replacement (or maybe just a new Schaffner), but ... how should I remove it? Is this a drill-out-the-rivet job? I've never had to deal with this before.
2. opening up the 1st of the three, everything looks really pretty good, a little dust is all. The only date codes I can find are on the EPROMs, 8849 and 8850, meaning the 49th and 50th week of 1988, one assumes. Is there a date code anywhere else? I wonder if the date code is not necessarily when the EPROM was programmed but the revision of the firmware. Seems unlikely tho. Thoughts?
3. The electrolytics all look just fine. I'm going to spot check ESR on 2-3 largest ones, if the ESR looks ok, should I replace anyway? Opinions?
From the date code, and somebody's post here about list price in 1988, the one I'm working on (it has option 1, two channel output) cost nearly $7000, which is nearly half the tuition for my sophomore year at Cornell!
Thanks all!
