  1. I have a set of KLH Model 5 crossovers being recapped. one crossover, the two rotary switches are busted and need replacing. This has been an impossible search thus far to find either a used set or even a suitable replacement of any sort.

    Is bypassing the switches an option? Would this just take the adjustability away and rely on the amp? I am anxious to get these suckers back to producing great music and have been on the hunt for some switches for a couple months with no luck.

    How many failed? Point-to-point or pcb? There's a point-to-point Model Five xo on ebay now. That should give 2 usable switches if you have that style xo. Search for "KLH Model 5 Five Speaker Crossover"

    I grabbed that in hopes it was a match, but it isn't. 

    Two failed on same crossover.

    A final thought on the Fives: After recapping mine I was a little disappointed. They look beautiful and were "supposed" to be KLH's answer to the AR-3a. They just didn't excite me. So now I'm trying to get rid of some of the many speakers I've acquired, and found a buyer for the Fives.

    Pulled them out of the corner where they've sat for over a year to inspect them before packing. Then I noticed what I had never looked for before: The cloth woofer surrounds were quite porous. So, following the Service Bulletin #60 I applied Roy's sealant to the woofer and mid surrounds, and to the woofer dust cap. Fired 'em up and WOW! Now THAT's what they should sound like! Just as good as my AR-3a's and AR-91s (now I'm sort of sorry I sold them wink.gif).

    SO...Before considering esoteric caps for your Fives or other cloth-surround speakers, seal the woofer surrounds. It makes a MAJOR difference!

    One more note: Although the Service Bulletin says to seal the dust cap as well, I don't think it's necessary to use Roy's non-drying sealant there. The caps are quite rigid. Aleene's Tacky glue or white glue used for foam surrounds should probably work fine.

    Happen to know where to find some pots for the model 5 crossovers? Mine are being recapped and the pots have failed on the back side and need replaced. 

  4. My Model 5 crossovers are in the middle of a recap job, it was found that the potentiometers have failed and need replacing. Anyone know where to find some?

     

    This thread is great and detailed! Once the recap job is complete I will be refinishing the cabinets! They are in pretty good condition, but a little TLC will be nice. Hopefully we can find some potentiometers to replace the broken ones.
