MAD parts

The big cap and coil roll off the low end to the midbass unit, the small cap feeds the tweeter.
The 200µF is a Callins electrolytic, the best available 30+ years ago. It's shot now.

The 3.5µF is a mylar, after 30+ years the ESR will probably be high, replace it with a polypropylene.

The new tweeter you are going to buy will probably be a bit louder than the original. You may need to up the resistor value a bit, and lower the cap a bit too.

Tack this in parallel with the 200µF:
