    Default Cracked Crossover Board - SC60 Ceiling Speaker

    I've got a cracked crossover board on my SC60 Ceiling speaker. Polk only sells a board with all the components soldered in and does not have any blank boards. Is there any way I can solder material across the cracks to complete the circuit? The board itself is flimsy.

    As long as you can figure out the schematic and not cause a short, you can use regular chassis wire from radio shack.

    Good advice. You could also try gluing the board together with super glue before you add the jumpers to give it a little more strength.

    I'd try a little 5min. epoxy instead of the super glue.

    +1 on the jumper.

    I did this on an Lsi9 following a bad shipping hit. If you follow the trace carefully and then you shouldn't have any trouble.

    Default Finally - The SOLUTION

    I spoke to Bob Hovland who advised the following steps.

    1. Scrape off the film on either side of the break with a razor blade to expose the copper surface.
    2. Carefully solder some chassis wire/capacitor wire across the break for every circuit. The wire once soldered to the copper on the board not only completes the circuits but also holds the board in place.

    Thank you for all of your suggestions ! They all helped lead to a final result that works extremely well.
