I recently procured a pair of original JBL 4663's. These are 4560 cabinets with the 2405 tweeter, 2461 horn and E 130-8 mid/low speakers. These speakers are serviced by a 3106 crossover. The speakers are in really nice shape and all original except the wiring has been removed from the crossover and hooked to a 1/4 inch jack, presumably to be hooked to an external mixer? So I want to restore the original use of the crossover. I have looked up all the old instructions and catalogs on this, buy have failed to find a clear diagram on how to wire the speakers to the crossover, and then add a speaker wire input. Might some one give me guidance on how to properly wire these crossovers back up and get these fine old boys back in service? Thank you, James.
