KLH Model Six recap: blood, sweat & tears

Hey, all. OK, I realize this subject has been addressed in other threads, but I'm still confused about what to do. First off, I love these KLH 6's with my little push pull 15-watt maggie. But the left speaker suddenly sounded dull, and it turned out the tweeter was not working.

The tweeter itself seemed OK, so I was left with recapping the crossover. I have a couple Clarity 8 and 4 ufs. Luckily, my model is newer than the completely sealed version. So now that I've removed the woofer and gotten into that glob of glue where they drowned the crossover, the only thing coming unglued is me.

Tried a heat gun to melt the epoxy and made a mess, because I didn't know what I was doing. Same with the alcohol method (although a shot of vodka might have helped). So I set about chiseling it out with a hammer and screwdriver. Thinking it was a cap, I'm afraid I chiseled out the switch box. Maybe the only cap here is the shotgun shell looking thing beneath a resistor. See black arrow pointing to the switch I probably destroyed (the blood on the coil is mine):IMG_0308 2.jpg

Also, there is a metal clip attached to the inside that looks like it could have held a cap--but it's empty.

I would not mind skipping the hi-lo-normal switch if it would simplify things, especially since I'm pretty deaf to high frequences on one side, if it would simplify matters. I would probably just keep it on hi or normal.

If anyone has any ideas what I should do next, I would be grateful! Now I have to go get a tetanus shot. :rflmao:

Just chip or knock the tan stuff out of the opening. At least one of the
caps is on the upper left corner in your picture. An equivalent switch
should not be hard to source at a big box hardware store.

This schematic shows 2 2uf caps and a 6. Whatever, just match the old ones,
though yours look to be all paper.

Thanks, RxDx. I think I've also seen that larger cap as 8uf, but I will plunge back in and plug away at it. Would you know if I could use a KLH 17 crossover? I've seen that somewhere. There's a pair on eBay for about $20. But I have caps and at least what used to be half a brain, so before doing that I will try one more time.
 
Looks the same except for the big cap and the inductor for the
woofer.

You could drill the glue plug to make it easier to remove. I suggest
staying right at the edge of the opening.
 
That single cap embedded in the epoxy stuff is actually both of the 2 uF caps. You’ll have to chip all that stuff away to expose the leads. Then install two 2 uF caps.

Yeah, I think I get that now. So those 2uf caps will be wired together on one end with separate leads divided by the resistor in between, right?

Yes. I cut the wires right next to the original cap. The black wire should be connected to both 2uf caps and the two red wires to be connected to each of the caps individually.
 
Thanks, Hornbostel. Since I ordered paper/oil caps their size may be a minor problem, but hopefully I'll be able to take it from here.
