Thanks, Mot! It appears that your dual 3/4 cap was either installed incorrectly at the factory, or the "follow the label" theory may not be correct. The KLH 5 schematic confirms the diagram posted by Kent to be correct, so your 4uf cap and 3uf cap should be reversed relative to your photo(s).

If there is one constant when it comes to KLH speakers, it is the awful red and black capacitors. I have worked on 3 pairs of KLH 5's, a pair of KLH 17's and a pair of KLH 23's in the past 2 months, and 6 out of the 44 capacitors measured anywhere near their proper values...and when they did, ESR was crazy high. I often wonder if some of these caps were within spec when they were new.

jessi...I don't subscribe to the pricey Mundorf world, but Madisound is another good source for those. https://www.madisoundspeakerstore.com/m.d.l.-capacitors-page-5 Madisound has an excellent variety of other brands as well, with their electrolytic and film MDL brand caps being a particularly good/high quality value.

Thanks everyone.  I'll follow the diagram posted by Kent.

@jessiAV, I hope I didn't hijack your thread...

Here is the underside of my crossover.  I have circled the positions of the 4uf and 3uf soldered leads.

Hello Kent and Roy.  Thank you both for your help!

Kent, you are correct, I am trying to determine which lead is 3uf and which is 4uf.  I'm not sure if it will be helpful, but here is a close-up photo of the cap in question.  

I'm starting to wonder if it would matter much if these leads were inadvertently switched.

Thanks again. Tom

@JKent et.al, I am preparing to recap a pair of Model Fives.  They are the later variety with the PCB.  My question is regarding the "+3 +4 uf" capacitor.  I am assuming that the two leads on one end are joined and soldered.  How do you handle the soldering of the other two leads... where do you solder the 3 uf lead and where do you solder the 4 uf lead?  Hope this makes sense.  Here is a pic of the cap in question.  Many, many thanks in advance!

The last three numbers are the width (36, 42 or 60 inches).

Thank you!

I ordered a yard of my best pick from Ulster Linen. It arrived this week and if I can figure out what I did with my staplegun (which I haven't seen since before we packed up to move to Portland eight years ago!) I have a spare pair of 3a frame boards I can mount it to.

It's undyed, unbleached natural flax linen. We figured out a while back that it's 20ct. Here's what the loose yardage looks like.

Genek, this fabric looks great!  Do you have a link?  I've been to the Ulster site but can't find this fabric after trying to sift through the choices.

The fabric I've been using is a 100% linen with a 19 and 20 thread count.  Starts very light but soon mellows down.  Could be tea stained.  I remember my first pr. of fives out of the box were very light so I left it as is.   If you look at this online it does not show well.  It is ILO41 at fabrics-store.com.

Thanks for this info!

Did you purchase the “OATMEAL?”

[Another Seventeen restoration]

Hi Kent,

Not sure if this will be helpful, but...

A while back I restored a pair of Seventeens with the same grille cloth.  One of my grilles also had a small stain that resembled rust.  Like you, I also tried to clean it to no avail.  Turns out the stain was isolated to just one horizontal thread of the fabric.  Eventually that portion of the thread disintegrated into powder.  I really don’t believe it was a conventional stain caused by a spill.  Instead, I believe something in this weave is subject to oxidation and eventual disintegration.  I ended up pulling a stray thread from the back of the grille and threading in to replace that missing portion.  Not perfect, but worked pretty well.
