FYI,you can tell the approx. manufacturing date by checking date codes on
several components,like filter caps,power xfmr,and ICs.  
8644 would be 1986,week 44

I'd say your7603is a fairly "new" one,that's a high serial number.

Well, I see what *could* be date codes like 8352 and 8413 on a few
trannies, and 8439L on a PS cap. I can't believe they built these
clunkers well into the mid-80s! Everything about this scope screams
70s!

The stink is more like stale cigarette smoke, which is a lot worse
than electrolyte. I know electrolyte when I smell it.

PS cap replacement is a challenge given the fact none of the readily
available replacements I found have matching pin configurations (plus
is usually centered rather than offset to one side). Sprague
apparently had their own system, and bending pins is not an option
here.
