Apbt121999 Posted November 10, 2019 Report Share Posted November 10, 2019 I realize this is old but I just picked up two KLH Model 5 which both looked to have had some work done to include caps relaxed. One said 1986 in the back. Both workers were marked July 1968. They sound pretty good to my ears but wondering if I should go through a recap. I included pics of the two. Some smaller blue caps in one. Looks like the small black and red ones which I understand are problematic were left alone. Any input would help Well can’t post pics over 200mb. Will need to resubmit Quote Link to comment Share on other sites More sharing options...
b_sdaddy Posted February 20, 2020 Report Share Posted February 20, 2020 Not going to need much help, (hopefully), as these detailed instructions and photos are just what I need! Off this weekend to collect a pair of 5's. Here's the photo the seller posted. Looking OK for a total refurb. Quote Link to comment Share on other sites More sharing options...
JKent Posted February 20, 2020 Report Share Posted February 20, 2020 The Fives are really nice speakers. I'm curious what kind of modification was done to that one. The 6 screws--3 above the mids & 3 below--are not original. Woofer surrounds should be sealed with RoyC's goo. Makes a big difference.

b_sdaddy Posted February 20, 2020 Report Share Posted February 20, 2020 Should I be worried? From the placement of the screws, it looks as if something "structural" may have occurred. From the state of the cabinets, looking shinny, I think they've been cared for. Hopefully nothing drastic lurks within. I'm collecting them sunday without auditioning them. For €50, it's worth a shot. I think Roy has stopped making his goo and can't find anything on ebay. Hopefully won't need it. First caps, then cabinets.....then investigate further thz woofers, if I feel they need it. Quote Link to comment Share on other sites More sharing options...
JKent Posted February 20, 2020 Report Share Posted February 20, 2020 Don't worry about the goo. "Vintage-AR" sells it on ebay but he's on vacation. You might ask the seller about the screws. Did he add bracing? Did the sub-enclosures for the mids become loose and that was the fix? Probably not a big deal--sorry to panic you.

b_sdaddy Posted February 21, 2020 Report Share Posted February 21, 2020 Sadly the seller is deceased. His Daughter is selling everything off. Judging by the other stuff, he was "one of us". Just found Vintage AR - have sent him a message, although there are no items in his shop? I assume he's in the US. I'm in Belgium, so probably price prohibitive to send? cheers Quote Link to comment Share on other sites More sharing options...

He won't be back until March 18 and I don't think he ships overseas. You might send CSP member RoyC a message. He makes the stuff for Vintage AR and might be willing to send you some but there is the cost of postage. If he can send it i"First Class Package International" it should be about $15 USD but if it has to go Priority Mail it would be more like $40 USD. Or just wait until you have the speakers and use the 3-finger test to test for air leaks. If there are no leaks through the surrounds you should be OK.

b_sdaddy Posted February 21, 2020 Report Share Posted February 21, 2020 Intrigued. What is the three finger test? Quote Link to comment Share on other sites More sharing options...
JKent Posted February 21, 2020 Report Share Posted February 21, 2020 Sorry. Sometimes we talk in code. An acoustic suspension speaker must be air-tight. To test this, put 3 fingers around the perimeter of the dust cap and push the cone in. It should return slowly (maybe 2 seconds). If it springs right back there is a leak. Biggest culprits are the gaskets behind the drivers and the cloth surround. KLH recommended re-doping all woofer surrounds: http://www.classicspeakerpages.net/library/klh/other/klh_schematicsservice/klh_service_bulletin_60.pdf Quote Link to comment Share on other sites More sharing options...
b_sdaddy Posted February 22, 2020 Report Share Posted February 22, 2020 That's what I do to check the VC rub. I never really looked at the speed at which it rebounded. thanks. Quote Link to comment Share on other sites More sharing options...

Not sure if this is proper, but I used Aleene’s Tacky glue, 1 part glue/4 parts water, to redope my surrounds. This was suggested on a different post. Where, I am not sure. Memory failure again.

b_sdaddy Posted February 23, 2020 Report Share Posted February 23, 2020 I use a "tacky glue" for the surrounds. Thanks for a plan B, if I need one! Quote Link to comment Share on other sites More sharing options...
b_sdaddy Posted February 23, 2020 Report Share Posted February 23, 2020 Well after a few hours in the car, I'm back from, (what I think to be), a successful trip? The photos the seller posted, did not do the condition of these beauties justice - They're mint! Absolutely stunning cabinets which I'll just wipe over with some furniture polish. The grilles equally so, but I'll have a go anyway, just to get them 'like new'. The 6 screws are part of an internal box that has been fabricated. (from the same mtl. as the board). It looks 'factory' but may very well be DIY, but by someone who knows his stuff. Q: Was the box, shrouding the two mids, a std. feature? Perhaps he's just added the screws to reinforce the box? Anyway, hooked them up, and quite obviously, they need a recap. Lovely bass though! Sadly, not too much work here for me, but the Leak Sandwiches are keeping me occupied.

Great find! 5 hours ago, NewBill said: I used Aleene’s Tacky glue, 1 part glue/4 parts water, to redope my surrounds. This was suggested on a different post. "Danger Will Robinson!" Only use Roy's goo. If you can't get it, use nothing. All the other stuff that has been tried eventually hardens to some degree. The result is ruined woofers (sorry NewBill).

b_sdaddy Posted February 23, 2020 Report Share Posted February 23, 2020 Found this on ebay. There's a KLH 5 with exactly the same, six screws. Something was obviously being done at the fabrication stage for this not to be a DIY job by owners.....?https://www.ebay.co.uk/itm/KLH-model-5/332483942001?_trkparms=aid%3D111001%26algo%3DREC.SEED%26ao%3D1%26asc%3D225114%26meid%3Dacaa654d03514489bc4b74d4e4d6c3b6%26pid%3D100675%26rk%3D1%26rkt%3D15%26mehot%3Dpp%26sd%3D332483942001%26itm%3D332483942001%26pmt%3D0%26noa%3D1%26pg%3D2380057&_trksid=p2380057.c100675.m4236&_trkparms=pageci%3A727a8369-5677-11ea-a0de-74dbd180348e|parentrq%3A73a50aba1700a4b77cefb990fffb823e|iid%3A1 Quote Link to comment Share on other sites More sharing options...

b_sdaddy Posted February 26, 2020 Report Share Posted February 26, 2020 So then, my first initial thoughts. Well, they're OK, but nothing special....... Oh how wrong I was. After a few 'pop' vinyls, I was seriously unimpressed. I decided to change two things; the genre and the volume. This time CDs, and classical: Piano & cellos with volume!! WOW! I've listened to these pieces dozens of times, and now I hear parts of the orchestra that were previously not there. Rounded, warm, nothing missing except a bit of sparkle at the top end - going to recap as a matter of course, so will address this. But it's the slight increase in volume that beings them alive. Seriously impressed. My Realistic T200 Optimus's are crude by comparison & are headed for a new home. Yes, they're capable and detailed, but they're so harsh by comparison. It's the difference between instant coffee & a quality espresso. Just can't wait to get them recapped and experience them 'as new' Currently my favourite speaker, but with parts in the post for my Leak Sandwich's & I'm also off to collect a pair of Wharfedale Dovedale 3's at the weekend, this may be short-lived!

JKent Posted February 26, 2020 Report Share Posted February 26, 2020 Great! I really like those speakers but I sold mine a few years ago. It was either those or the AR-3a's and the ARs go a bit deeper so they were the keepers. Sorry for repeating myself but on mine the cloth surrounds were dry and porous so the speakers sounded good but not great. Roy's butyl rubber sealant brought them alive!

b_sdaddy Posted February 27, 2020 Report Share Posted February 27, 2020 surrounds are fine, and as for deepness, I turned off my two subs as was not dissapointed. And for the small investment of €50/$50, I'm happy. Caps will cost the same, but for €100, you're not going to find much better out there!

b_sdaddy Posted March 1, 2020 Report Share Posted March 1, 2020 So the cosmetics are done. Just waiting for the caps. Long term might get the surrounds done, dependent on costs US to Belgium! Happy with the result considering outlay. Definitely 'keepers'. Quote Link to comment Share on other sites More sharing options...
