Brad - just curious if you used a meter to check the new capacitors and resistors you installed to make sure they were correct as labeled? Maybe you received some that were not labeled correctly? All of the ones I ordered were exact when I rebuilt the crossovers in mine. But... you've got me wanting to find another set to rebuild!

Your speakers look great, and you're correct, these speakers sound awesome. Those ground rivets are an issue, on mine, I wired them all together so that the grounding was not dependent on the rivets connection to the metal plate. Glad you got you issues sorted out.

Oh, and yes, they're worth repairing. See my post about about rebuilding my crossover and refinishing my cabinets.

Have you tested them directly and not through the crossover? A bad crossover component or rotary switch could make it seem like they're bad when the drivers are actually good. The crossovers probably need rebuilding anyway.

Do you mean the switches? There are on potentiometers. I don't know where you'd get those. Try cleaning them up with this stuff: https://www.amazon.com/gp/product/B00006LVEU

Wow - I just realized that I didn't coat the dust caps on the model 5's I rebuilt.. thanks for the reminder! I had to order another small jar of the stuff from Vintage AR on eBay: https://www.ebay.com/itm/ACOUSTIC-RESEARCH-SPEAKER-CLOTH-SURROUND-WOOFER-SEALANT-KIT-ALSO-KLH/193701935734

Kent - looking at the other recapped images and info, I assumed I was supposed to replace the dual caps with 2 caps. Seems to work well. Fred

Hi I just wanted to say thank you to the information on this site. I just finished restoring and recapping a pair of KLH Model 5s. My uncle had given them to me several years ago and they have sat in storage since then, he got them from a house he was cleaning out - I assume the original owner. A few months ago I moved something and saw them and took a picture of the label and was going to sell them... that is until I searched and found this site and realized what I had! The drivers were in great shape (needed re-sealing which I did with sealer from vintage-ar on eBay). I refinished the cabinets with Watco walnut Danish Oil. I replaced the caps with Dayton Audio audio grade caps and replaced the resistors with Jaztzen Audio Superres and Mills resistors. I also, after reading about ground issues, ran 14ga wire between all the ground tabs. I replaced the lead wires from the xovers to the drivers and ditched the wire nuts and soldered the connections. I also used DeoxIT D5 on the rotary switches. They sound absolutely amazing! One thing I came across is that one of the crossovers was wired wrong - one of the caps was connected wrong. I drew out the connections and was having a time matching it up to the factory schematic provided on this site... so I picked up the other xover and it was wired correctly! I guess it had been wrong since 1970!
