Curbside Score!!!

[jheu02]

Annual bulk trash day, he shoots...he scores!

EPI 100s with the inverted domes - just need refoam, will do caps and probably better wire too. Cabinets in nice shape, as are the grills. Didn't open them up but it seems they used 10uF. Confirm?

KLH Model 17s these are a bit rough overall but the drivers do work. Not the best sound right now, so I'll definitely need to recap. The attenuation switch seems to work however, so I doubt I'll replace the resistors unless there's a compelling reason to do so with modern ones. The caps look to be paper and wax types, "Temple" from Mexico, and if you look closely at the one soldered to the switch, it has two leads coming out the one end, just one at the other. Is this just a jumper to ensure that the total capacitance load will always get to the tweeter regardless of switch position, and if so, could I rewire with the jumper across the switch terminals?

Is there anything else going on with this crossover? The caps are 2uF, 50V (at the switch) and 8uF 50V inserted in the wiring. When I redo them I'd like to just go with 1 10uF cap and keep everything neater at the back of the cabinet. I'm not sure how they came up with the crossover of 1500Hz, but does this wiring arrangement have something to do with it?

Also, the woofers are pretty dirty (see pic) what's the best way to clean this up? Could I use a light bleach solution to kill any mold/mildew that's getting ready to bloom, or would Lysol be better followed by a thorough drying on a sunny day to also expose to UV?

Yes, the correct cap for the EPI is a 10uf.

Make sure the woofers are actually dirty, the coloration of the woofer cone makes it look dirty even if it isn't. I'd be hesitant to use any liquid cleaner on the woofer, I'd suggest a vigorous dusting followed by some time in the sun. The crossover is in fact 2x2uf and an 8uf. Do a search for KLH 17 renovation and you'll hopefully find a very detail thread on re-doing the crossovers, stick with the 2x2uf and 8uf (2x4uf in parallel is a good alternative since 4 is way more common than 8), don't try to second-guess the KLH engineers. Check the resistors and if the resistance is still correct don't worry about them. Enjoy your new speakers.

What are those tweeters pictured?

Thanks for pointing me to the rennovation thread. Will be adding to that thread as I get into my restoration. The 2 x 2uF caps is a little bit of a shocker though, as the one marked 2uF sure seems small to be a double cap. I took a closer look at the photo though and there is an extra "2" followed by a blank space and then 2UF50V.

My serial numbers are AS17 56350 and AS17 56743

i just used the 1% tolerance 10uF in my EPI's and they sound super sweet!! Great score!!! i read this forum 40 times if not a day and i hear of all these sweet scores....I have had a couple but i need to live where you guys live.

I just saw the cabinet pics...wow those look nice for being a curb.

 

[hardrock94]

Wow... good rescue....

Way to go! I love my EPI 100s, especially now that I've got 100wpc going to them.

Those woofers look like they have cloth surrounds. If so, They may only need redoping to seal the cloth.

Spot on advice on the caps. And don't worry about the woofers - they're supposed to be butt-ugly. Probably just need some re-sealing of the surrounds. I think the how-to on that may be in that thread you already found.
