    Identify this crossover?

    Below attached is a crossover I obtained for $20.... It is/was advertised as a 4312A crossover, however the cap numbers do not match what I have for the A, and the L-pad controls appear to be for a L-100, etc. Can someone confirm what this is?

    It appears to be stamped "100" on the circuit board, FWIW.


    What does the back of the input plate look like? Looks larger than the 4312A inputs I've seen. And the plastic L-pad mounting looks different than any L100 I've seen. Then I have neither in my inventory.

    It looks like an L96/L112/L150A network to me but I can only read a couple of the component values.

    Lightbulb Crossover Identification

    I had a chat with the "gentleman" who sold it to me.... He's keeping it; I'm not paying for it, and the search for a spare pair of 4312's or 4312A's crossovers continues.....
    Thanks for the kind assistance. We'll see what happens.
    I assume I can post a "Want to Buy" for the desired crossovers in the for sale section, so I'll head that way later today.

    I'm going with the L100 My L112 is slightly different in placement of the inductors.
