Here's the link: https://community.klipsch.com/index.php?/topic/187633-jubilee-k-31-e/&tab=comments#comment-2444078 The part number is #1067961

This thread has gotten pretty confusing because three different people have asked for help dating their Epics. The second one was Epic-Heritage: Although Dave knows more about Epic speakers than I ever will, I think he missed the part in your post where you stated that you had red and black colored wire visible through the ports. So my understanding is that your first guess of version 3 was correct. I'm certainly no expert, so if there is another reason Dave @wvu80 thinks it is not V 3 hopefully he will help me out and clarify. Also nobody bothered to respond to a third request for Epic info, this one from newbie derbygoose, probably because it seemed this thread was finally concluded. Derby, it looks like your serial number is from early 1996, so I think that definitively means Version 3, if I'm reading the Epic dating guide correctly. If I'm wrong, hopefully someone will post a more accurate assessment. I'm apparently trying for the title of OCD posterboy today.

I know there are more than a few fans of great female vocalists reading this thread. My favorite new artist in this category is Madison Cunningham, who is not just an amazing vocalist, but also an outstanding guitarist and songwriter. She is only 22, and her first "real" album "Who Are You Now" just dropped a few months back. She did record some earlier amateur material when she was younger, but that was before her talents as a songwriter and guitarist had fully emerged. Her voice is one of those that cuts right through you, and her guitar playing (though understated) always serves the song. It's as though Joni Mitchell and Richard Thompson had a love child. Her song writing is, like her voice, beautiful, personal and unique. I agonized over which of the many stellar clips I should post of her frequent performances on "Live From Here" over the last three years (some going back to when it was still called "Prairie Home Companion" ). Here's an original song from late 2018 that gives a quick snapshot of her talents called "Plain Letters". For those that aren't familiar, her oddball wingman in this clip is Chris Thile, probably the greatest mandolin player in recorded history, who occasionally channels Pee-wee Herman when he is performing. If after viewing this you want more Madison, below is the link to her full set at the Palace Theater in St Paul, Minnesota where she opened for Andrew Bird just two months ago on Valentine's Day (before the virus abbreviated her ongoing tour) . It's a complete, live performance--mistakes, happy accidents, and no overdubs. To me, that's what live music is all about. If you want to pull up individual songs from the show, here's the set list and time stamps: 0:10 Beauty Into Clichés 4:46 Dry As Sand 9:20 Trouble Found Me 13:23 Pin It Down 18:34 Higher Ground 24:29 I Close My Eyes 29:40 L.A. 35:00 Something To Believe In 40:32 All At Once Thanks to Full Range for starting this thread! triceratops

Asking $8K (plus shipping) for a pair of Altec Valencias is comical (and I'm an Altec fan). This has vanity project written all over it. https://www.audiogon.com/listings/lisa27ij-altec-valencia-864a-vintage-horn-speakers-a-true-survivor-pair-full-range

Thanks for the follow-up, Ike. No dispute about the value of the Jensen P15LL speaker. I've owned a number of vintage Klipsch pieces with these and they are wonderful drivers.

I'm not trying to nitpick, but it appears that the auction for the Jensen P15LL is starting at $200 https://www.ebay.com/itm/1-Klipsch-PWK-15-4-OHM-WOOFER-KLIPSCHORN-SPECIFIED-JENSEN-P15LL/264718113035?hash=item3da26dd90b:g:bTMAAOSwh55erMrc

Very true! I don't even use the FM section of receivers (I prefer Sonos for radio), but it sure is cool having extra inputs, like hook-ups for two turntables.

Well stated, W&T. I will revisit the 330C when I get a chance. Going back to W&T's photo highlight above, it looks like the left positive terminal for speaker 1 is toast. I've seen those red terminals break down more than the black ones, maybe more vulnerable to sun damage?

Over the years I have owned examples of each of the Harman Kardon Twin Power 930, 730, 630 and 430 receivers. I found out about this series here, thanks to HDBR's extensive posts on the topic. The 430 (like the other three models) is a great match for Klipsch because that first watt is just as clean as the ones that follow when you crank up the volume. Part of the design is a really robust power supply, as all four models have a separate power supply for each channel. All you have to do is lift one of these receivers to know it is a serious piece of equipment. As has been pointed out, the differences in wattage between the models is not that dramatic at moderate volume levels. The thing you would probably notice most is that the tuners improve as you go up the line. What is worth clarifying is that although the Harman Kardon 330 is cosmetically similar, it does not have a twin power supply, so it is not really part of this series. The 330 is still a nice entry-level receiver, but not worth tracking down like the twin power units. HK also made some solid-state integrated amps with twin power supplies around this time, but they must have sold in much smaller quantities because they don't seem to come up for sale as often.

Hi Dian, Thanks for the explanation. I thought that was what you were saying in the original post, but I wasn't certain. I am surprised that the pictured receptacles have been removed on your other pair of KLF20's. You might also add a photo of the bottom of one of your cabinets showing an empty hole where the receptacle should be. A picture is worth a thousand words, as they say. I'm not sure the "Alerts" section is the best place for your question--maybe Technical/Modifications? Is there a thread on the KLF Legend series like there is for the Epic series in 2-Channel Home Audio? I recently purchased a pair of Klipsch Epic CF-4's and they appear to have the same threaded receptacle arrangement as your KLF20's. So if there is not a dedicated thread for KLF owners, you could post something in the Epic thread that might generate some good advice. If you haven't already done so, I would check in with Klipsch to see if those threaded receptacles might still available from the parts department. it's possible those parts were used on more than just the Epic and KLF series (maybe someone who knows can chime in). I would not call these pieces "feet" because they are intended to have feet or spikes attached to them. The thin caps that you have pictured that slide over the receptacles are also not technically "feet" even though they can serve that purpose. They are really just shipping covers to protect the threaded receptacles in transit. There may be similar caps available at your local hardware store, sold as furniture end caps. While you're waiting for a definitive solution for your missing hardware, I would put some small self-adhesive felt pads on the bottoms of your KLF's to protect the wood from scuffs and scrapes. These can be easily peeled off once you find what you need for a more permanent solution. I hope to compose a long post about what to thread into the receptacles to serve as feet for the cabinets, for folks that are missing that hardware, but I'll leave that for another time and place. -triceratops

Dian, Congrats on finding the KLF20 speakers you've been searching for! Just to clarify your question: Are you looking for the threaded receptacles on the bottom of the cabinet that are pictured in your photo? Or are you looking for feet (or spikes) that screw into these receptacles? Or the plastic caps pictured that slide over the receptacles? triceratops

It's always hard to tell from just one photo, but at this angle the numbers look to me like they have been wiped away with a cleaner or solvent rather than faded by the sun. Again, it could just be a quirk of this photo. There are a lot of earlier Heritage pieces that have fading on the inked part of the label, but fortunately many of those have duplicate serial numbers stamped into the cabinets.

This is awesome! Thanks so much for your help, Jim!

Jim, Thanks so much for the prompt and detailed reply--very helpful! triceratops

Absolutely beautiful! Great score, Labalish!

Thanks, Tony! I think 1962 is a fair approximation based on the letter code, and that's what I suggested on the Alerts post regarding this pair. But I'm hoping Jim will weigh in with the actual production date. That's because this is a transition period between code formats and date code documents on the Forum led the owner to state they are 1955. If I was in his place, I'd want a definitive answer so that's what I'm asking for.

Hi Jim Hunter! As the title says, I'm looking for birthday information for these two single Klipschorns #1610 and #1545 The two speakers have identical drivers--I'm guessing they were manufactured within about 6 months of each other? Mono no more--they are going steady now as a stereo pair and are making beautiful music together! Thanks for any info you can provide!

Hi Jim Hunter! Like the title says, can you please provide the log info for Klipschorns 1A827 and 1A828? This pair is currently advertised for sale on Craigs List in Portland, Oregon, but they have been incorrectly identified as 1955 due to misinformation in the Forum Serial Number Document which you pointed out earlier this month. I hope you can shed some light on the actual date for this pair. Thanks! \

My earlier post was written before reading that hanksjim1 had already identified incorrect date code info on the forum and brought it to the attention of Klipsch Historian, Jim Hunter. Please see "Early Klipschorn Serial Number Confusion" in the "Ask the Historian" section In short, the serial number changeover from 4 digit numbers to letter codes happened in 1963 not 1955, and the "A" code was not used from 1955 to 1963 Hopefully someone can unlock the serial number document and fix these errors. I'll ask Jim Hunter what the correct date is for this specific pair of vintage Klipschorns listed on CL in Portland And shout-out to hanksjim1 for being way ahead of me on this--sorry for my redundancy everyone!

An Oregon shout-out to Mungkiman for posting this quote from the 2-Channel Archives. His post called this revised document to my attention. I haven't been on the board much lately, so I don't know if some of these changes have been made in recent years. I also don't know if what I'm about to say has already been beaten to death in the Forum--if so, I apologize. There are a number of reasons why I think the information cited by this quote is in error. Maybe some other late 50's-early 60's vintage Klipschorn owners can pipe in. First off, using the "A" code for years from '55 to '63 doesn't make any sense from a record-keeping perspective, and other parts of the archives directly contradict this. It's possible that "A" could have been used for a while or intermittently, but there is just no way that 4-digit serial numbers could have stopped in 1955, which is part of the premise. According to other company records the Electro-Voice T-35 tweeter (designated K-77 by Klipsch) was first installed in Klipschorn #1445 on October 15, 1959. I recently sold single Klipschorn #1610 to a Forum member in Portland, so naturally it had the early version of that tweeter. I believe that #1610 speaker was either late 1960 or early 1961, because it also had the K-33 Electro-Voice woofer EV 15WK ("K" designation made specifically for Klipsch). According to company records, the last of these EV woofers was used in March 1961, when the company changed to Jensen. But the cited letter code timeline would suggest that the #1610 Klipschorn was built before 1955 because of the 4 digit code, and I don't believe that. I am aware that drivers can be changed, but this particular Klipschorn is one of many examples available to support what I am saying about the 4-digit numbers. I suspect this consecutive serial number pair of Klipschorn speakers in this ad is from 1962, because of the "A" code. That's probably why they have K-33 Jensen woofers and K-77 Electro-Voice T-35 tweeters. This is not to take anything away from what is clearly a beautiful and historic pair of speakers and the CL poster's description was based on what should be reliable information from the Forum.

I think the Luxman R-117 is a truly great receiver and it sounds excellent with Klipsch. One potential problem to be on the lookout for: there is a relay inside that is part of the signal path. Over time the relay contacts can get contaminated and this makes the signal break-up intermittently. It's just a bad connection but it can actually sound like distortion, similar to what sometimes happens with a dirty pot. The fix is supposedly pretty straightforward, although I personally have not done it. The cover is taken off the relay and then a sheet of paper wetted with a solvent is pulled back and forth between the contacts. Or some folks use a very fine abrasive paper, and then a solvent on regular paper. If all this fails, the next step would be to replace the relay itself. I hope you get it worked out!

Thanks for the encouragement, River! The 2.5's are compact and seem like they could be useful for various applications from sides or rears for home theater to mains for a small stereo rig. They also have threaded inserts on the bottom to allow them to be mounted on a wall in the Batcave, etc.

Since the buyer is a one feedback eBayer, it makes you wonder if that might be a shill bid that was intended to increase the sales price. It will be interesting to see if they get reposted by the seller.

On another note, isn't the finish on the baffle some kind of heat-shrink plastic? Has anyone seen the fronts done in white before like they are on this pair? It really makes the horn, woofers, and ports stand out--looks very cool!
