I have been restoring a set of Calinda's and Corelli's.
While I was at it I made schematics of the crossovers.
The values of the inductors were measured by a Meterman 37XR.
Calinda crossover SP1055
I am sure the big inductor is 3.5mH (both crossovers had the same value)

Corelli crossover SP1052.
The version I have does not have a tapered inductor.

Any comments are welcome.

Not too surprisingly, the Calinda tweeter aB section is identical to the 104 aB. The bass section is different because of the different cabinet/bass unit. The 104aB had the tapped inductor first 2/2.7/3.5 mH (for the mid range adjustment), then the 5uF to ground, and then 0.6mH and 10R in parallel to the long throw SP1039, so similar. The Calinda used the SP1054 which I don't think was used in any other systems.
