Another collector in the area had the basic service manual for the 2515 which is now up under http://bitsavers.org/test_equipment/genrad/25xx
I'm working on postprocessing the softwar manual this morning There is a second volume 2515-0102 which contains the schematics. I hadn't noticed this before, but Tucker Electronics closed this past summer :-( who used to be a good source for manuals. I also was given a 2517 unit this morning. > On Fri, Dec 7, 2018, 6:16 PM Al Kossow via cctalk <cctalk@classiccmp.org > <mailto:cctalk@classiccmp.org> wrote: > I doubt I'll ever find docs for it though. >
