Two separate caps.

That simple? Wired in parallel? Edit: Now I see it. One lead of the 8 uF goes to the resistor and one lead to common and the 16 uF goes to blue and common. Tks.

Odd Capacitor
I recently picked up a pair of the KLH 24's myself. I looked at the capacitor with three leads and went WTF? It was a bit unusual to see a cap with 2 taps for different values. That was an interesting way of only having to put in 1 cap into the cabinet instead of 2. I guess it's back to parts express to buy another pair of caps.

I've got the 22's. Same dual cap set up. Like you, I had to return to parts express. 22's and 24's are the same speaker from everything I've read. Nice sounding little bookshelf speakers. Good solid bass too. You'll enjoy them after the recap. FYI, Vinatge AR on ebay has the correct compound to put on the cloth surrounds. Bass response will be even better after the surrounds are done.

I saw the info about the proper dope for the surrounds. They don't sound too bad now, but I was thinking of doing that to them eventually too. Not that some of the "homebrews" that people have come up with are bad, but I want to use the correct dope, if possible.

I actually had great success using a flexible undercoating (spray kind in a can) on some 23's. But after reading further that a lot of these various fixes seem to work in short term, but who knows how they'll hold up over time I started to order in the proper dope for all my other KLH's (23's second set, 6's,5's,17's, and 22's). I tried the permatex on cloth surrounds on some Optimus 1's. Big mistake. Ended up scraping those woofs and found original replacements. Optimus 1's were RS answer to the KLH 6. Probably closer to the 17 in actuality.
Nice under the radar speakers.
About to recap my KLH 24s (same cap set up as above) and just want to confirm that white rectangular component is a cement resister. If so, 8 ohm, 10%, 2 leads? I've already got the caps.

I found my sketch I made of the crossover when I took it apart. It shows a 3 ohm resistor 7 watts as the original. I put a 10 watt version of a 3 ohm in my replacement, even though it didn't need to be replaced. I confirmed it with a picture that I took of the original.
Thanks very much. By the way, that pic you took of the before and after recap is printed in color and sitting beside me as I type. It is as close to a step by step as anyone could expect and very helpful.

I also had posted the schematic that I drew up. See post #11.

Just a quick report back. Replaced the caps and resistors on the KLH 24's. Piece of cake thanks to you, Boto. Hooked 'em back up. A little muted at first but opened up nicely in about an hour's playing time. I'm guessing they'll probably be a little further break in going forward.
Well a problem seems to have emerged in one of the KLH-24's. Recently unpacked them from a move (CT to VA), hooked them up and not getting sound from the woofer of one of 'em. Opened it up, all connections were solid and correct. Removed the woofer and measured resistance at 5.35 ohms which isn't perfect but should be within tolerance. Checked out the caps that I replaced and they're measuring in spec. Any and all assistance appreciated.
Edit: tweeter appears to be fine.

I'm assuming you've already switched to the opposite channel on your amplifier and checked balance etc. Otherwise, frozen voice coil? Does it move when you push on the cone?
Excellent call and I do thank you. Frozen voice coil. No movement whatsoever. I'm assuming the fix is to replace the woofer?

How big is that woofer? 8"?
