Before you go much further on your 38-690, you might want to read this:

I would replace that 1 uF tweeter cap with a 4.7 uF polyester cap. Also check the tweeter wiring as indicated in the link above. You will thank me later.
Regarding the 1.75 - 1.75 uF cap: I'm afraid I have no clue on that. I might hazard a guess and say that perhaps this was a World War II replacement when parts were scarce and repairmen were limited on what they could use for replacements? Again, that is just a guess.
