    L100 Crossover Help

    Can you point me to a wiring diagram of the L100 crossover itself? The crossover looks fine, but is outputting no sound to the midrange (the bass and highend are fine). Any suggestions? Thanks.

    If it's an L100A (has the square-flange LE25 tweeter, then the crossover is so easy, I can spout it off without even looking:\

    Tweeter section : 3uf mylar cap, feeding an L-pad, which then goes directly to the tweeter.

    Midrange: 8uf mylar cap, feeding an L-pad, which then directly goes to the LE5-2 midrange.

    Woofer: Direct wired from the input terminals (no crossover components whatsoever).

    If it's an earlier model, I'm sure someone will drop by with a link or a pic...

    The main reason for midranges not playing in L100s, is dirty, broken or burnt -up L-pads. I'd try jumping terminals "2" and "3" on the L-pad (the two terminals that are NOT the ground), and seeing if the midrange then plays. If so, replace the L-pad...

    Regards,
    Gordon.
