  1. 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.
  2. Kent, Thank you for the kind offer. A PM has been sent.
  3. I am two years into my love affair with my restored Model Eight! I was able to do much of the restoration myself with the kind assistance of Kent! I benefited directly from Kent's vast knowledge and generous nature... Thank You Kent! My questions for @JKent and other KLH experts is... Has anyone used an inrush current limiter (ie. CL80) in a KLH Model Eight? Would this addition be helpful as a way to extend the life of the on/off switch? Many Thanks!

    Thanks Roy, I'll have to try the HiVi tweets (when I get some extra cash...).

    Thanks Roy, Ever try the AR-18 tweets in the 4x? If so, how did they perform? What's your opinion on this pair? http://www.ebay.com/itm/170688729267?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1438.l2649 Mot

    Hi Kent. Yep, those are the tweets. Interesting idea... switching out the drivers and XO from the Avid into the better AR cabinets. Doubt I'll ever do it though. I'm too anal... whata you call 'em? Avid 4x? Hello Pat and Roy. While I'm not at all dissatisfied with the current output from my 4x pair using phenolic tweets... please describe the ways the sound is enhanced when using the AR-18 tweets. Do the AR-18 tweets require further modifications to the XO or are they a simple drop-in? ...and are these the AR-18 tweets you are suggesting? http://www.ebay.com/itm/Acoustic-Research-AR-18-BXi-Pair-Tweeters-1210064-0B-/170688729267?pt=Vintage_Electronics_R2&hash=item27bdd750b3 Mot

    Roy, thank you! I really appreciate your guidance! Dan, I did the following for the 4x's: Replaced the original rheostats (still scratchy after cleaning) with Ohmites. Installed new Dayton 20uf capacitors. Replaced the original tweeters (one was dead) with Phenolic Ring Tweeters. Applied Restor A Finish with 0000 steel wool, followed with Feed N Wax.

    Gentlemen, I wired the other speaker and it is functioning the same as the first. I’ve been running the pair for a while now and they are sounding great... just as each of you suggested they would! Thank you very, very much! I attached a drawing, which shows how I wired the tweeters. Please verify that I have wired these correctly. This forum has been an invaluable resource! Many, Many Thanks!

    Thank you both! I really appreciate your info. and suggestions. Later today or tomorrow, I'll wire the other speaker and compare. I'll report back after I'm done. I suppose my experience with the AR4x pair I rehabbed has left me expecting something similar from these HiVi tweets.

    Okay, resized my pics... here they are...
  11. I'm having trouble with the HiVi Q1r with inductor in my AR-2ax. Some history: I replaced the caps with Daytons (6uF and 3uF as recommended by Roy C.). I replaced the original pots with Ohmites (RHS15R). When I wired it up for a test today, the tweeter sounds like a very, very weak transistor radio even when played at higher volume and the Ohmite turned all the way up. It does respond to adjustment from both the amplifier and adjustment from the ohmite... it just remains very, very weak and tinny. I can't figure out how to resize the huge digital pics I took. But I wired everything as shown in these two pics. I have checked, double checked and triple checked the wiring. All wiring matches these photos. Any and all suggestions and guidance will be very much appreciated.
  12. Thanks Kent. When I rehabed my 4x's, I was unable to bring the original pots back to life. While researching an answer to the problem, I stumbled across a pair of Ohmites on eb@y. Long story - short... I fit them in... shielded them from the fiberglass... and they are really working great. Now, while working on my 2ax's, I can only get the original pots to work intermittently. I know the Ohmites are not easy to work with... but I'm so happy with the way the 4x's turned out that I am determined to make them work in this pair as well. Thanks again for helping to make this site such a wonderful resource. Mot
  13. My first post. Hello Kent, Many Thanks to you and everyone here! With information I gathered here (and at audiokarma) I was able to rehab a pair of AR-4x's. It has been a very satisfying experience... and I'm now working on a pair of AR-2ax's. Are you still selling some Ohmite pots? If so, I am very interested in buying them.
