    KLH Woofer 116808

    klhaudio.com sells a Kendall model, though it looks different from what you have. Why do the woofers need replacement? It looks like the surrounds are blown. If that's the problem, surrounds can be replaced.

    Okay, did a little work on this... front page of my site: http://aphenos.net/ drawings index with links to drawings: http://www.aphenos.net/electronics/speakers/klh/AR_Drawings_.html

    So here are both links: Index: https://www.classicspeakerpages.net/IP.Board/applications/core/interface/file/attachment.php?id=20559 Drawings: http://www.classicspeakerpages.net/library/acoustic_research/special_sections/drawings/drawings/ Those could replace the post by Ken Kantor in the Library that leads to a non-functional Flash file. The index could have a link on the same page that has links to the images. At some point I'd like to make an index that has direct links to the drawings.

    KLH serial number decode?

    They are most likely from the 1971-72 time period
  7. I listed the three models as equivalent, and what I've read in Audiokarma suggests that's true for practical purposes. You commented in that thread, but I couldn't tell if you noticed audiojones' statement that KLH went to the more common (smaller) magnet sometime into the production run of Twelves. Of course, measuring the two types would reveal the truth.

    Briliant! I've not been able to find the images here. Here's a direct link to the index. https://www.classicspeakerpages.net/IP.Board/applications/core/interface/file/attachment.php?id=20559
  9. Someone else in another forum suggested this for switch replacement: https://www.mouser.com/ProductDetail/CK/A30305RNZQ/?qs=h7H1bHRqGz%2BI/XAEF%2B2b7A== This is included for reference, or if you/someone wants to bypass them legend says switches are set at ccw and that they turn cw. so here are connections made at the three positions IMO mids ccw 12-1 4-5 8-9 (decrease) middle 12-2 4-6 8-10 (normal) cw 12-3 4-7 8-11 (increase) tweets ccw 12-1 4-5 (decrease) middle 12-2 4-6 (normal) cw 12-3 4-7 (increase)
  10. This guy sells what seems like 80%+ of the vintage gear on the Richmond list, usually at full retail. Twelves are nice speakers, you just need to decide if they're that nice. Never dealt with him, no idea if he'll haggle.
  11. Can't help you on xos, but production (or at least availability) dates for the Five went through 1977, according to buyer's guides of the time. Same for the Six, Nine, Seventeen, Thirty One, and Thirty Two.
  12. If you weren't aware, Model Five and Twelve tweeters are equivalent. Model Six, Seventeen, Twenty, Thirty, and Thirty Three will fit, but they have different voicing. I haven't compared the two variations side-by-side, so I don't know how much difference there is.

    the latest I've been able to verify PIO caps is about system # 18xxx A few people have been able to knock out the front baffle of the early systems from the back and save the grill cloth. There are apparently a couple of screws or some kind of fastener on each side of the front about midway down. Either way, entry from the back isn't all that difficult. I put a pair of Fours on saw horses, terminal plate down, to chip out the epoxy tub. All the shrapnel fell on the floor, not in the cabinet.
  14. That 20 ft coax could be picking up some signal. Here's way more information than you probably need, but the coiled-coax balun might help. http://ham-radio.com/k6sti/balun.htm
