Bill Hausmann Posted October 29, 2006 Share Posted October 29, 2006 I know we have a few x-over experts here. A friend just picked up a pair of 62 K-Horns. Without going nutz, what upgrades to the x-overs do you guys recommend? -Bill Quote Link to comment Share on other sites More sharing options...
Guest " " Posted October 29, 2006 Share Posted October 29, 2006 Maybe none, if they already have been re-freshed, whats their current status? Quote Link to comment Share on other sites More sharing options...
rcarlton Posted October 29, 2006 Share Posted October 29, 2006 Change out the old capacitors with new capacitors. Quote Link to comment Share on other sites More sharing options...
J.4knee Posted October 29, 2006 Share Posted October 29, 2006 There are a variety of options but if you were looking for universal applicability I'd say go with Al K's universal upgrades. They are affordable and worth every penny. Or as suggested here do a cap replacement or maybe contact Bob Crites or Dean G on the matter.<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" /> Quote Link to comment Share on other sites More sharing options...
funkyhambone Posted October 29, 2006 Share Posted October 29, 2006 were they the mahogony ones in brooklyn? Quote Link to comment Share on other sites More sharing options...
BEC Posted October 29, 2006 Share Posted October 29, 2006 I think the '62 Khorns would have a K-500-5000 crossover with a 16 ohm tweeter. Rebuild would be the best solution if that is the case. Bob Crites Quote Link to comment Share on other sites More sharing options...
Bill Hausmann Posted October 29, 2006 Author Share Posted October 29, 2006 They are STOCK as stock gets. ... and in DAMN good condition!!! Yes, these are the ones from Brooklyn.. You had to see the stairs we had to come down. The guy we got them from, couldn't have been a nicer guy... He just couldn't make it work in his LR. Just as well, he had a pair of Genesis hooked up to an 8B that I drooled over..... ;-) Bob, When you say rebuild... do you mean start from the ground up? I can see the caps, but do the inductors go out of spec with time? Quote Link to comment Share on other sites More sharing options...
BEC Posted October 29, 2006 Share Posted October 29, 2006 Just the caps really age and get bad. I would expect everything else on the old crossovers to be fine. The K-500-5000 went through several revisions over time, so hard to tell exactly what circuit those might have. Some have autotransformers and some don't have them. No matter, I would expect everything except the caps to be good. Bob Crites Quote Link to comment Share on other sites More sharing options...
BEC Posted October 29, 2006 Share Posted October 29, 2006 Here is a schematic I drew of the K-500-5000 from some '63 Khorns. Sorry for the poor drawing, but I just quickly drew it while rebuilding the set of crossovers. Might be the same as the '62 Khorns.

Al Klappenberger Posted October 29, 2006 Share Posted October 29, 2006 Bill, You might look to see what squawker horn is in them too. It may be the old K5j. If they are that old you might do well to replace the entire top section as well as the crossover. Much better stuff is availbe now. If you do that you can move up to a new crossover design rather than patching up an outmoded one. AL k. Quote Link to comment Share on other sites More sharing options...
Bill Hausmann Posted October 29, 2006 Author Share Posted October 29, 2006 Thanks guys... I'll tell you as much as I can remember from briefly seeing them today. The mids are the pv-5v something alinco drivers I think. There were 2 caps "soldered" in parallel. 1 more cap with screw on nutz over to the right and the inductors looked like spindles. I didn't open the LF cab. AL, what do you mean by "Replace" the top section? Quote Link to comment Share on other sites More sharing options...
Al Klappenberger Posted October 29, 2006 Share Posted October 29, 2006 Bill, Yes, you describing a very old speaker. I'll bet it's got the old K5J horn in it. By the top section I mean everyting but the woofer! I would go for an Altec 511b midrange horn or my Trachorn plus Bob's tweeter. The squawker driver could be an Atlas PD-5VH. Replace the network with my original ALK "Universal". You can do all of this yourself or I can make you a complete drop-in top section. Al K.

seti Posted October 29, 2006 Share Posted October 29, 2006 I would listen to the speakers for a while maybe update the caps. It would be a shame to deviate to far from the original parts. I mean this speaker has been around in its present form since the 60's. Nice score.. Congrats... Quote Link to comment Share on other sites More sharing options...
Bill Hausmann Posted October 29, 2006 Author Share Posted October 29, 2006 Thanks again..... unfortunately, they're not mine... my close friends though. We had to go take my truck to go pick them up. I think if I came home with those, they would stay, and my @ss would be out on the curb! It was bad enough when I came home with the Conwalls!!! I hear what Al is saying, but I don't think he'll go for a horn swap out. I pretty sure he would like to keep the horns stock. I agree that those caps have to go! which one of you guys keeps caps that can be used in that system in stock? Quote Link to comment Share on other sites More sharing options...
BEC Posted October 29, 2006 Share Posted October 29, 2006 I can fix you or your friend up with caps. Bob Crites bobcrites@mac.com Quote Link to comment Share on other sites More sharing options...
PrestonTom Posted October 29, 2006 Share Posted October 29, 2006 Congratulations on the new Klipschorns! You have been given some good advice about refreshing the caps on the crossover. This is small step. You can order the caps from Parts Express and it will only set you back $15-20. I believe Solen caps would be fine. You will soon get advice about swapping drivers and adding elaborate crossovers, spending huge amounts on tube equipment, etc. All this can get very expensive and the price to value ratio is difficult to determine ahead of time. So let me give my other piece of advice. After you swap the caps, don't do anything. For the next several months just concentrate on making sure the cabinets are in corners and listen to them. Enjoy them. There is always time to tweak later on. But first you should get to know them. Later on if you need to tweak, then you will have a better baseline for comparison. -Tom Quote Link to comment Share on other sites More sharing options...
dnodee Posted October 29, 2006 Share Posted October 29, 2006 Hey Guys, I'm the owner of these 62's. Bill is a great friend and tech and he spent most of the day with me today trucking out to Brooklyn, carrying them down two NARROW flights of stairs and then into my house. He even bought my Cornwalls so I could afford to get these. They truly look nearly brand-new. Just beautiful. We managed not to damage anything. They are type C- no riser.I can't even find a nick in the Ribbon Mohagany anywhere. The story is that they belonged to a Doctor in CT and were in the same place in his house since 1962. The Guy I bought them from got them not too long ago from the estate but couldn't get them to work in his room (I agree, it was just too small) I've got them in a 22 x 25 foot room with high ceilings and nice corners. I have baseboard heat so I'm going to have to get some rubber or foam to seal the tailboards. I would like to update the x-overs but not butcher anything. So maybe a cap replacement or can I swap out the whole crossover for a type A or something? That way I could always replace the originals if I ever sell (fat chance!). Anyway, to say I'm happy would be an understatement! Quote Link to comment Share on other sites More sharing options...
BEC Posted October 29, 2006 Share Posted October 29, 2006 Changing out the crossovers to a Type A would also require some driver changes. A replica of the crossover could be built or your old one could be rebuilt. Bob Crites Quote Link to comment Share on other sites More sharing options...
dnodee Posted October 30, 2006 Share Posted October 30, 2006 Bob, Do you build and sell "new" 500/5000 crossovers I could buy to drop into these babies? Quote Link to comment Share on other sites More sharing options...
Al Klappenberger Posted October 30, 2006 Share Posted October 30, 2006 Bill, That's a different situation. I suppose you will have to do whatever the guy who owns them tells you to do! It shoulnd't be hard to talk him into a "repair" like replacing caps. "Upgrades" are always a judgment call! AL K. Quote Link to comment Share on other sites More sharing options...
