    Recapping L36 Decades

    Here's a picture of my L36 crossover. Schematic shows 3 uF, 6 uF, and 16.5 uF. Are the two horizontal caps in this phot 3 uF each? then big one is the 16.5 uF?

    OK - think I figured it out. Those are the three caps - 3, 6, 16.5

    All the wiring confused me at first. Serial number of the caps are in the schematic.

    Here's one of my crossovers with the new caps. I used Daytons. 3 uF crossed over with Russian millitary grade 0.047. Two 3.0 Daytons for the 6. And 2 Dayton 8.2's for the 16.5 (16.4 )

    My second L36 has different L-Pads and layout. Before recapping second I did some A/B'ing in mono. The recapped speaker is smoother and less shrilly. I couldn't listen to these through my Sui 890DB for long before listener fatigue would set in. I'm thinking the recap may take care of this and is why I went with Daytons. I felt Solens may be too bright. And so far the bypass cap sounds great!

    what is the value of the resistor?

    where can I get a schmatic?


    On my l36s for some reason the original owner thought it a good idea to remove the resistor,

    Now I want to restore the l36's to their original state.

    Except I'll need to buy a set of mids and tweets to complete the project.

    radio shack parts just don't do jbls any justice

    I rebuilt mine using Troels Gravesen's schematic. It was a huge improvement.

    No doubt...

    It's a great way to breathe new life into perfectly good transducers.
