  2. Today we had a beautiful autumn day. I was out with the leaf blower, cleaned the rose beds. Then I have already received orders for speaker cables again. Yesterday I had cooked chicken soup , which was enough for 2 days. Now I have to listen to Tangerin Dream´s " Force Majeure " 1979 , it´s a clear cut record , excuse the bad condition from the cover , I bought this record in june, twentyseventh in 1980 so this record is almost 41 Years old. Sounds pretty good .......

  3. You should know better ‘Heel. Both of us are too old to risk a ladder mishap. Although I did climb my 24 ft. extension ladder for some interior work, I not only didn’t like doing it I knew I shouldn’t have. If you can buy fancy Dan tubes for your hi-end tube amp you then can pay someone for your high wire work. Much, much cheaper than a catastrophic fall. And beside, you still owe toasters to several people, me included. Falling from a ladder is poor excuse to get out from under a toaster debt. .

  7. 4 beautiful young women came across a deserted pond. They decided to go skinny dipping. The owner of the land was out working in the field and heard laughter. He grabbed his bucket and went to see the commotion. Upon arriving, one lady yells, "We aren't getting out till you leave!" The farmer yell's, "Oh I didn't come to make you girls get out, I came to feed the alligators!"

  9. As we all know, the world of audio marketing is full of blather, lies, scandalous mis-representation and a host of other scams, flim-flams and cons. Here's the latest to amuse me. A $5,600 (gee-what a deal!) record clamp. The price alone is an assault on the senses, but the verbiage to justify the price is both hilarious and nonsensical. Enjoy: "A legendary Shun Mook product now being made in very, very limited numbers. This record clamp is made from extremely rare pieces of dried ebony briar. The extra heavy century old ebony root which were immersed in the swamps of Africa has a unique power that no other wood possesses. The vibration generated by the diamond stylus in the vinyl groove besides inducing an electroflux through the phono-cartridge also excites the ebony molecules, causing it to resonate. This in turn is feed back through the stylus and is reproduced as expanded sound staging, enhanced separation, sharpened focus and enriched tonal balance of the music. "

  14. In the fall of 2019 my Father-in-Law dropped off a Sansui TR-707A Transistor Stereo Tuner Amplifier as one channel was very weak knowing there was a chance I'd be able to diagnose and fix whatever fate this amp suffered. Over the past two years I'd occasionally open it up, chase down a lead, and then give up when a more interesting/less challenging project came along. It was always hanging out in the back shelf of the workbench, looking at me with sad puppy dog eyes but knowing it would be a possibly pointless road to go down I hesitated. Fast forward to six weeks ago when a friend dropped off his NAD C356BEE which was DOA - he fried a few resistors/diodes/capacitors due to a speaker short. Once I had it up and running again I hooked it to the Heresy IIIs in the main system and was duly impressed. I was a little too close minded running my Elekit TU-8200 to think solid state could sound so nice! So I took it upon myself to consider the Akitika kits before realizing I might get the 34 pound beast in the basement working for much less money and have a good story. A little background gleaned from the internet and my wife's recollection of childhood stories came to a reasonable conclusion: my father-in-law purchased the unit from the base PX in Vietnam and the serial number appears as a 1965 date code so it matches up. From the on-line manual this is an 18WPC Class AB transistor amplifier and apparently was the first transistor amp that Sansui exported (it also has a really interesting (to me) topology but that isn't my strongest knowledge so feel free to read up on that. My troubleshooting discovered that there was no signal reaching the outputs so I started working backwards reflowing solder points. As the pots were scratchy I took out the can of DeOxit and sprayed down the pots which addressed the scratchy sound on the working channel but I was still left with a single channel amp. I began playing with signals and determined that the offending channel was working, again, nothing to the output. I even pulled the power transistors and determined all four were in spec - I was happy to find that as the transistors are long since out of production and there aren't any easy replacements or NOS units available that I can easily find. Going on a whim I checked a handful of capacitors and found one on the offending channel was reading as an open circuit. I'm not an electronics whiz in the least, but I like buying stuff to feed my audio addiction and who doesn't like assembling a bill of parts and getting stuff in the mail? I assembled a list of 74 capacitors for the pre-amp, amp, tone control, and power supply circuits and 22 hours after ordering from Parts ConneXion the box arrived. I pulled the replacement caps for the one that read open (and its channel twin), the iron, and....SHE SINGS! I've since gone through and replaced about a third of the caps on the pre-amp board and a handful on the output side. I'm doing this piece meal - one cap per channel per operation, then plugging everything in to check. The workbench system consists of a CD player and KG1s (rebuilt crossovers in those). How does it sound? I really like it. The bass control offered is out of this world. The treble is clear and well defined and reveals a few details I had not heard in music previously, although it seems to be hot - I have it turned down slightly on the tone controls. Channel separation is as expected given the specifications (abysmal by today's standards) and imagining is fairly poor to non-existent. The hiss during song breaks is noticeable. Even the tiny little KG1s have great bass weight and extension to them. I'm really impressed with this beast. Future work: 1) Finish the preamp recapping project, move on to the output recapping, and the power supply recap (power supply is first on the list to be honest). I also have capacitors for the tone controls and might get to that. 2) Replace the speaker terminals. Currently uses a slotted screw which accepts spade connectors, I'm replacing with 5-way binding posts. 3) Replace the RCA jacks. The built in RCA jacks have a flare, pushing out the sleeve of any connector attached. 4) Replace the non-polarized power cord with either a polarized two-prong cord or a grounded IEC cable. There isn't enough room to mount an removable plug so I'll hardwire the IEC power cable. 5) I've been unsuccessful in tracking down a replacement knob cover for the balance pot; my back-up plan is to slide the volume knob over to the balance pot and go with an aftermarket knob for volume that is consistent in appearance of the unit. 6) Replace the rubber feet on the outside of the case which have deteriorated due to age. 7) Trouble shoot the lights - while all lighting is functional it is not very bright. As much as I like this amp, if my father-in-law wants it back I'll let him have it. But I really hope he doesn't.

  17. I have seen these discussions turn into arguments but I hope we are adult enough to discuss a topic civilly. I would like to think I am good at my job which has me working with lab grade test equipment and working with extremely complex systems, I really have to know what I am doing including exactly how capacitors function in all regards and choosing the best types to be put into space for the rest of it's life. Often we do tear downs of our old products and go through them to see what can be improved upon for future revisions etc... Let's address the elephant in the room first. Someone that has a notion in their minds that capacitor a is far better than capacitor b and is anticipating an "improvement" upon something will have expectation bias. There is a HUGE psychological element to this where books could be written about that aspect alone. Whenever we remove this element in serious blind tests the drastic hearing difference claims fall apart. The mind starts to play tricks on you on what you hear and you no longer are absolutely certain about a specific capacitor making any difference at all. This is comparing functional parts of correct value appropriate for the application. If you have failed or drifted components then yes of course there could be a sound difference. Some very old caps indeed could have drifted off spec but still function fine but the filters have changed voicing and this could be audible, today you can order a tolerance of 1% where the older style large oil filled types klipsch used may be slightly off even from the factory when new. You mentioned ESR, great lets discuss this and how it applies to what we are doing here. Lot's of techs use an ESR meter, this tool almost always tests at one specific frequency and it is almost always at around 100Hz. Let's also put some numbers to the filters and discuss how an increase in ESR effects the functions. Let's look at the AA crossover for the tweeter, specifically the 2uF and 245uH second order high pass filter. We will use a two frequencies to view and model what is happening, first 100Hz which should be attenuated and not reach the tweeter and second 10kHz which should pass through the network and reach the tweeter. Now a modern film capacitor will have a very low ESR, usually much less than 1 ohm, this is usually stated at 100kHz on a datasheet. It is important to note the ESR changes with frequency so when discussing ESR it is vital to note the frequency to which it was tested, if tested with a meter it is typically around 100Hz. Let's put some numbers to the parts at the two frequencies. 2uF capacitor impedance - 100Hz = 795 ohms 10kHz = 7.95 ohms 245uH inductor impedance - 100Hz = .15 ohms 10kHz = 15 ohms When 100Hz signal enters the network a voltage divider of 795 and .15 ohms forms and less than 1% of the signal gets to the tweeter. I have tested many of the old klipsch oil type capacitors and their ESR can reach up 8 ohms at 100Hz, yet at 10kHz it is still less than 1 ohm, this is why I say it is extremely important to test the capacitor ESR at many frequencies and not just use an ESR meter which will give non-engineer types the wrong impression. But let's assume that the ESR has risen to even 10 ohms at 100Hz, how does this effect the crossover filter? It will add to the 795 number giving us 805 ohms of impedance. How does this effect the filter? It actually rolls off MORE of the lower frequencies since the impedance is slightly higher, but really it makes no difference because we don't want 100Hz getting to the tweeter and the capacitor with the high ESR still does it's job well, actually better since impedance is slightly more. Now a 10kHz signal enters the network, we have a divider network of 7.95 oms and 15 ohms, this means 65% of the signal gets to the tweeter. Here is where ESR does matter, IF the capacitor does have more than 1 ohm of impedance you may start to get losses, the modern film caps klipsch uses in the 1994 Chorus will certainly not have an ESR higher than 1 but we are talking about the old big oil filled caps so let's just add 1 ohm to the numbers making the 2uF capacitor 8.95 ohms. We have now only dropped 1% from 63% of the signal reaching the tweeter to 62% reaching the tweeter. When dealing with the AA crossovers of 1982 that I own 5kHz and up were all less than 1 ohm of ESR but at 100Hz the 2uF caps measured roughly 5 ohms ESR and the 13uF was 2 ohms ESR. I do not lose any sleep that at 100Hz the ESR is 5 ohms more because it is moot in how the cap functions in the circuit, and as I have actually proven it will actually HELP what we want to do by decreasing the low frequencies to the tweeter by having the impedance slightly increase at the lower frequencies so replacing them you actually worsen the goal of the part by allowing a very small fraction of the low frequencies pass through, but I doubt the 5 or even 10 ohms will make an audible difference since we are already below 1% of the full signal. It is great to see folks discussing technical things like ESR and capacitors but you need to understand ESR and also the application before making judgements. I get it though, when someone shows you some reading on an ESR meter that a capacitor that should have a low ESR has an ESR of 5 ohms many would assume this is bad, and it very well would be in other applications but it is vital and I cannot stress enough understanding the application is of utmost importance. As I have shown the slight increase in ESR at 100Hz is moot, you go from 795 ohms to 800 and with in filter network makes very little difference, and the actual difference it makes is actually a good thing as it helps impede the low frequencies to the tweeters. IF you do have grossly high ESR at 5kHz and above with the capacitors then I would start to agree to replace them but of the older style capacitors I have measured from my own heritage series speakers and friends of mine they seem to still have a low enough ESR at the frequencies of interest which is 5kHz and above. I actually put more weight into the actual capacitance value as that will make a much more drastic difference than an increased ESR at low frequencies because as I have shown that actually HELPS our cause. I can go into this further and bring phase into account but I am sure that will bore most people, my concern was to give people reading a better grasp at the function of these capacitors and using real numbers to show what is happening so this ESR scare doesn't cause anyone to lose sleep. If you do have a local tech that is scaring you with ESR numbers have them plot the ESR over a wide range of frequencies so you can make a better judgement of to replace or not replace because a meter that measures ESR at low frequencies tells us nothing. The reason the meters test at 100Hz or 120Hz is because that is what our power is transmitted at and so they figure that is what is of importance, they don't know you want to test caps in a speaker crossover network.

  19. Since we're in a Klipsch forum... I've dropped Klipsch woofers into the rear deck of my e46 BMW & figured out how to put other Kilpsch speakersin the doors without cutting metal. The only thing I wish Klipsch made is a 2.75" midrange speaker. This is only the rear speakers before the doors were installed and the head unit really needs to be replaced. It sounds flat to me.

  22. Thanks for the kind words, and @jcn3 - more guts shots for you. Last night I decided to put this back on the bench and do some more work. I'm old enough to know my eyes aren't great in the evening after looking at screens all day so I decided to focus on some of the bigger caps on the output side. I'm always impressed with how small modern capacitors are - for example, the pre-amp circuit has a dozen or so 30uF caps in voltage ratings 6V, 10V, 16V, and 25V that for simplicity in the Bill of Materials are all now 25V rated (and for future consideration, are all 33uF as good luck finding a 30uF cap). The output side has a handful of 500uF / 25V caps (now 470uF/25V) and 200uF / 25V (now 220uF/25V) axial caps that are spanning between terminal strips that now look comically small and have resulted in using some hook-up wire and heat shrink tubing on leads. I looked further at the speaker terminals - my parts bin had a "ganged" set of binding posts (red/black) with 3/4" spacing that was too narrow to fit; but in a "light bulb" moment I realized that the L/R binding posts were spaced vertically 3/4" - so the binding posts were disassembled and will be installed in a black/black and red/red pair (speaker terminals are mounted on plastic and the gang holding the posts is plastic. After doing the output section I decided to do some work on the pre-amp section. I thought to myself "I shouldn't do this - my eyes are tired and I can't focus and even the 3.0x magnifiers aren't cutting it" [I'm in my late 40s so yeah, getting old sucks] but I did it anyways. After doing one cap on each side with much difficulty (I was heating the wrong solder point - first sign of I should have stopped) I powered up to static only to realize I hooked up audio cables wrong when rearranging the workbench. But even on fixing it I got some "pumping" in the audio chain so....I stopped. I had been heating a B378A transistor pad so I was worried I fried one, but....Before work this morning I powered up the system to just check the pumping sound and it was gone....so who knows. Maybe the transistor overheated and took some time to cool. Might have a long meeting at work today that I can shop around for either NOS or replacements (looks like an AC152 or AC153 might do the trick). I also need to get some hot glue sticks. My kids used it to make their Halloween costumes this year and apparently got glue happy. - but I need to put some dabs down to hold some of the new caps in place. I also plan on revising the install of the two blue caps. Going to leave the monsters they replaced in the board, but hot glue them down and heat shrink the leads.

  23. Need to finance a new set of Jubs to replace my underground Jubs. Yea, you want photos, that will come forthwith (when I get a round tuit) and I know that you are a bunch of cheap skates like me. But I THINK these prices are not too far out of line. PM if you want to discuss please Location is 78414 Price is pickup but I will entertain help (labor) with shipping. CT-650-T in white new in box (never opened). I used one pair but not the other. $350.00 One pair black KI-396-SMA II. No boxes. Purchased as a trio with the third modified by the factory to be used as a center between the Jubilees. The 'used' pair for sale (yes, I connected them as surrounds for a few minutes) just didn't fit in the room. $2000.00 Cornwall IIIs in walnut ... this is for a set of three. I used all three as the front LCR for surround duty but since moving into the new place with the Jubs one pair is used for my bedroom system and the third is relegated to closet storage...no boxes. $3500.00 for the three Parasound P-6 preamp and A23+ amp. Have boxes and have been used for approx an hour while I was testing rooms to see if I could make a dedicated Parasound / Jubilee room. I found I didn't have a second room to support that. I have a second A23+ amp that has indeed been used at some gatherings and now power my outdoor speakers but it's not the one offered (just in case you have seen me with these and think oh, that's BS he has used them). $2000.00 for the P6 and A23+ combo in factory packaging. SOLD Boxes you ask? Well for 30 plus years I held on to every box for electronics I had purchased. When I bought this place I scrapped everything I didn't have a immediate need for which included boxes out the azz.

  28. Klipsch has policy on selling proprietary parts. They may only sell these to registered AL5 owners as a replacement. Someday they may offer a complete upgrade. But been a while since seeing these kits. The Well documented B&C DE120 is a drop in replacement. The Citation driver now used by Klipsch (reported by people who have seen them) may require crossover adjustments. Crites and DaveA sell horns with these drivers. Installing them made a huge upgrade in my LSII. The new ones used by Klipsch might be even better though.

  31. I love Bob, I have spoken to him many times over the phone, great guy!! He himself will tell you and it is his FAQ that "all good caps sound the same" period. He explains it very briefly but accurately that if the ESR has increased you will have losses, that is why when you replace a bad capacitor with a known good one in these they almost always say it's brighter which it is. I just tried to take that into depth with my previous response, yes if at the frequencies of interest the ESR has risen too high you will have losses. Many of the older heritage series speakers with those large metal caps can go high and it is a good idea to replace them, luckily the last time I tested the caps in my crossovers they were acceptable by my standards and the speakers sound great so I left them in. Music, electronics, amps and speakers have always been a passion and hobby for me. I have a gross thirst for knowledge and information I just don't stop reading and looking through schematics. I have many local friends in this hobby and combined with how much gear has gone though my own hands along with theirs I like to think as myself as well informed. Please don't bow out, your opinion is extremely important and just as valid as mine. I do have theories why some of the "boutique" capacitors sound different in crossovers compared to any good capacitor as Bob and myself call them. I may go ahead and when I have time go into depth on that especially if anyone else has an interest. Like I said I have luckily been able to get my hands on lots of things including these very expensive capacitors because regardless of my advice some of my buddies want these caps in their crossovers and amps. Which brings me to say that even for no reason at all you just want special parts that is totally cool, this is a hobby after all and we are meant to get joy out of it and so if using fancy caps makes you happy then that is great. I have a stubborn belief that if you actually hear a difference it can be explained with physics and so that is my goal, only to find the truth with scientific methods.

  32. I had recently learned to check every so often. Had Farmers for the longest time, no issues, not claims, occasional minor increase. About 2 years ago, we finished the basement and made some nice home improvements that with the rise of the housing market we knew our value was going up (tax assessment increased over $40k in one year). With our daughter starting to drive, we decided to shop around. Ended up with USAA with more coverage, better deductible, and lower rate.

  37. I was and still am considering a tube pre, the Freya+. My system also does home theater duty but with an emphasis on 2-channel stereo, but it has to integrate with TV and movies as well. The Freya+ does home theater passthrough and it has a passive mode that can bypass the tube stage. So it's always been on my short list if I decide to go separates.

  42. I've replaced or had rebuilt several pairs of Chorus II crossovers pretty much always through Crites. Every time I was able to hear at least a slight change in sound more so with the complete replacement crossovers. Bass seems to improve / tighten up and overall clarity of the speaker they get more "clean" sounding. Admittedly these are usually slight changes that would go unnoticed if not listening critically. I tend to treat new to me used speakers like I do used cars; tune them up / go through them as soon as I get them and live trouble free short some unseen disaster. Do you have to replace parts before they're completely worn out or broken? Of course not but it gives piece of mind knowing things are right and will be for a very long time.

  43. Thanks Randy but, seems that crossovers seldom warrant the simple surgery to most before it should become evident. When and if it should become some, there will be choice made to that end. Thanks for the input but, in most cases of late, it is entirely premature. Anything further is to be considered as premature. Thanks!
