Refurbishing a pair of KLH model six speakers

I just picked up a pair of KLH model six speakers. Hooked them up and the woofers seem fine but both tweeters dead in the water. Found manual on the web but only had four pages. Question is do I want to spend a lot of $ fixing tweeters? ans. no. I understand that the caps go bad and that might be the problem. If so, where do I get the right caps and how do I get to the crossover to replace them? Only reason I'm asking these questions is that these speakers bring back memories.

Hi Guys,

I have a pair of Sixes I bought back in the early 70's from Tech HiFi a popular auidio boutique that started in Canbridge, Mass. Originally at MIT.

I replaced both my tweets as the originals were prone to failure when played at high volumes. I replace the tweets with high end Titanium domes and while at it I redesigned the cross over to cross at a slightly lower frequency to take full advantage of the sweet sounding domes in the midrange. I kept the original woofers.

I replaced the cap with Music caps and the coil too with an oxygen free Cu wire. I used silver solder, no wire nuts, and eliminated the resistors and switch, I replaced the thumb screws with Gold Bananas. Less is more.

Hey its 50 year old technology...the Sixes sound sweet especially on tube equipment which they were designed for. Legendary Kloss.
