In Topic: Need Help Dating KLH 6 Speaker

You have the early style Six, which was manufactured until sometime in 1963. The drivers are epoxied in. Replaceable drivers came after that. One way to tell the difference is that the later models had a recessed connection/crossover plate. The later style was sold until sometime in 1972.

Not hard to imagine an EQ in the amp circuitry after looking at the boxes wired to the Twelves.

It's amazing to me how much mileage KLH got out of the lowly 4" speaker. AR didn't even bother.

 

Those grille bases look like punched metal, and from the ad, I think they'd look pretty good.

 

I've seen this speaker auctioned a time or two, but not much else. Nice work, as usual.

Just to clarify a few points:

 

-No amount of vinegar will take care of most of the corroded AR pots out there. If caked, green corrosion has developed, there will always be pits under it. Sandpaper or a Dremel tool may be of help in these cases. If the corrosion is too bad I toss it.

Perhaps these were in the minority. I did use a small wire hand brush to help finish the cleaning, after an overnight soak in the vinegar. These particular pots hadn't lost much material, except for the rivet holding the round disc on this one.

Great catch!

 

I can't imagine your original woofer is beyond repair. But it might not be cheaper than a used replacement.
