  1. Thank you so much for your valuable advice in the successful restoration of my college (c.1974) KLH17 speakers. Special thanks to go @JKent, who was extremely responsive and patient. This began as a simple project to combine a castoff receiver from the household with my speakers, which had been in storage for 25 years, to use in my model railroad room. A little research, however, revealed the importance of replacing the capacitors on speakers that old. I didn't know my speakers had capacitors before this project, and I'd never worked with a crossover. But I took everyone's advice and decided to go for the capacitors. The hardest part was figuring out what to order, and you helped. Then it was discovered that the tweeters were both bad. Too much "Stairway To Heaven" in college, I suppose. So I replaced those with original KLH tweeters because @JKent explained why I should do that instead of generics. Along the way, I learned that I should apply fresh speaker sealant to the surrounds, so I ordered @RoyC's special sauce and applied that. The speaker gaskets were in excellent condition, so I reused them. I replaced the grill covers (one of the originals was torn). I still have the medallions, and I restored those. Finally, I treated the cabinets with teak oil (because that's what I have on hand). Oh, and along the way, I ditched the castoff receiver and bought a little mini-amplifier from PartsExpress just because my project had become worthy. It's awesome. I couldn't be more pleased with the final result. Here's a photo of one. They're somewhat separated in a crowded room, so it's hard to get them in a photo together.
  2. I saw those, but it says they're 4 ohms. Don't I need 8?
  3. How important is it to get KLH specifically? I see some other brands, especially Dayton Audio and Goldwood, that look good.
  4. Thank you and love the toe tag!
  5. That tweeter is dead. Thank you for your suggestions for what to test. I started with the tweeter because my soldering skills are good, even if I don't understand the circuit. ? It zeroed out on the ohmmeter, and connecting it directly to the terminals yielded nothing but the sound of silence, and I don't mean the Simon & Garfunkel song. I'm determined to revive these speakers, so now I'll be shopping for some 4-inch, 8-ohm tweeters. Recommendations welcome. And you don't know how much I appreciate your help. @jkent @IARbybody
  6. @Jkent, Thank you so much. You're the patron saint of my project. I'd wondered whether the tweeter might be bad, but I don't know how to test beyond the circumstantial evidence. Is it possible that the 8.2uf capacitor is bad? I have voltage going into it but not coming out. The voltage jumps with the music, it seems, so I can't give you a specific reading, but it's generally about 0.5mV, it seems to me. Except it's 0 on the speaker side of the capacitor. I'm glad you enjoyed the Monkey Man reference. That song starts running through my head whenever I work on this project.
  7. I am attempting to restore my college-era KLH17 speakers, largely relying on advice and wisdom from this web site. This project is pushing the boundaries of my knowledge, which is good but challenging. I'm sure it's my fault and not yours, but it's not going well. I replaced the three capacitors on the first speaker, and my tweeter is silent. The woofer works. The capacitors are from Dayton Audio and specs are visible in attached images. I left the leads at full length and used a metal clip for a heat sink between the capacitor and solder point. I think my solder joints were good. I covered the bare leads with heat-shrink tubing. I didn't remove the existing resistors, so their configuration is unchanged. I've drawn an amateurish diagram of my resulting wiring. I have a multimeter, but I'm new to it, too, and not sure what I should be testing. Thank you very much for your help. I'd come mow your lawn, if I could, to show my thanks.
  8. Well, it wasn't exactly a typo. It betrays my naivete, more than anything. And I haven't exactly figured out all of the wiring. I'd just spotted the big, solo capacitor and presumed it was woofer while the others were tweeter. In any case, I know how to replace it. Thanks to everyone for being so nice and helpful. Once I get time to return to this project, it's success will owe mostly to you.

    KLH17 Capacitors

    I'm progressing on refurbishing my KLH-17s. I purchased new, good-quality capacitors that are carefully matched to specs. I easily identified the 8uf capacitor going to the woofer. Otherwise, I'm a little uncertain what I'm supposed to be replacing. Based on everything I've read, I think I'm going to treat my two 2.5uf caps as a pair to replace the black-and-red cylinder on the left in my photo. I'll tie two leads together and attach to the common at the bottom of the photo. And then I'll solder one cap to each of two poles on the switch. Is this correct? Thank you in advance and thanks to everyone who answered my previous post. Special thanks to @RoyC for selling me woofer surround sealant and for some off-channel advice.
  10. Thank you so much! I've got to do those capacitors first, though. ?
  11. I still have the KLH 17s I purchased in college (1974) and am ready to put them back into service. They've been in a climate-controlled environment for all of this time and in a box for 20 years since we upgraded to something better. The cabinets are in great condition. I'm going to freshen them up with some teak oil, but that's all they need. One of the grill covers was torn, and I've bought replacement fabric for that. I have the original badges. I've read on this board and elsewhere about the capacitors, and I'll replace those. My question is about the speaker cones. I read suggestions about redoping or something like that. This is for the ring around the speakers and not the speakers themselves, right? Should I do anything to the cones? What product(s) do you recommend? Thanks in advance for any guidance.
