I believe everybody here will agree that electrolytic capacitors should be on the checklist for replacement, certainly in the power supply. Ceramic and signal-path capacitors will be a matter of much debate (like anything in audio) but electrolytic capacitors should all be replaced.

Finding ANY well regarded tube integrated amplifier could be troublesome and expensive in some places in the world. Tahiti, for example.

BUSINESS OPPROTUNITY! Sell easy to remove badges from run-o'-the-mill audio gear for camoflaging our other stuff! Who was casting those clear pie-slice logos? [H]

Cornwalls fronted by McIntosh solid state, in the living room of a good buddy of mine. (Also in the Detroit area as it happens... I smell a conspiracy!) I was being schooled at the time about dynamic decompressors (RG Dynamics) when his wife came scurrying through with a laundry basket: "How do you like your music, baby?" "Loud!" I've since owned (in order) Quartets, KG4s, LSBL LaScalas, KG2s, Cornwalls and LSBR (painted black) LaScalas, (speakerlab) K-Horns, Tangent 5000s, and Heresies. The Speakerlab Ks are upgraded with new networks and tweeters, and function as my 2channel mains. The LaScalas and KG2.2s are pulling mains and surround duty in my theater currently, the Heresies are in my workshop/basement. The KG2s are recently retired from workshop duty, and the T5000s are currently for sale. Cornwalls were sold at cost to a member here... they became Cornscalas I believe. The Quartets and funky black LaScalas were sold at a profit, and both sets of KG4s given away to share the love. See what you guys have done to me? [8-|]

Try the blue pill...

Manuals and specs are still available: http://www.klipsch.com/ksp-400-floorstanding-speaker http://www.klipsch.com/ksp-s6-surround-speaker http://www.klipsch.com/ksp-c6 The KSP mains are powered, meaning there'll probably be special setup considerations depending on your AV Receiver. Others may reply with more (or more useful ) information.

You should change his name to "Lucky"! Too bad he'll never get his tongue back in his mouth! ...... One of my favorite jokes of all time... "Free to a good home: Dog of undetermined age. Missing tail and one ear. Blind in one eye, walks with a limp. Answers to the name 'Lucky'" Of course, I believe I know the OTHER 'Lucky' joke you are reffering to, but I won't repeat it here!

Blue? Congrats, where's the pics???? Nope Walnut colored. Pics to follow - its' been pretty crazy personally and professionally, what with flying family in for a wake and my grandmother going very rapidly off the Dementia cliff, and career-ending disasters at work. Took me four days to get back to my own thread! Yep. Demo'd in a great setting, even tho I wasn't really prepared. No CDP or reference CD, I demo'd them with a Sony receiver and FM. The price was good enough that I didn't want to dawdle. Nope, absolutely bone stock. Took the back off of one and it smelled like new-sawn plywood, which is amazing considering these things are almost as old as me. I have long been a Heretic. I figured I may as well listen like one. Pics tonight I hope, unless I'm packing my office.

1977, HD-BR, original owner, stained by original owner, and (close) non-consecutive serial numbers. Priced right, tho, and they sound phenomenal. Condition is a qualified 'good.) Some scratches, but all in all good shape.

Interesting... So these are much younger than I would have thought given the age of the SS electronics associated with this rig.

I received a cold call from a buddy today... I have a line on something extrordinary, but the only way I have to date the stuff on insufficient info is the AL-3 X-over in a LaScala. Does anyone know when the AL-3 was used? Start and end?

Picture handling for the Klipsch forums Made Easy 1) Open a text editor like Notepad on your PC 2) Upload each picture to www.tinypic.com with resize set to 800x600 or 640x480 3) Copy and paste the resulting "IMG tags for forums" (paraphrasing here, not sure of the exact verbage) to Notepad 4) Start a new post here and paste all the IMG tag lines into said post. 5) Edit in the vicinity of the IMG tags to put descriptions etc over or under your pics.

There was a threadon AudioKarma on this critter - it's a hybrid with some tube tone in the front end and SS power - and poor at that. And, as always, don't believe the 2kw rating. A member actually bought one and tore it down, and had to reverse engineer grounding problems that resulted in audio noise. Here's the thread: http://www.audiokarma.org/forums/showthread.php?t=303638&highlight=pyle&page=7 (linked to page 7 where the teardown and listening tests actually begin.) It IS possible to get kilowatt audio amplification with tubes, it'd just take forty or more tubes of the KT88 class or a few ginormous power tubes with rediculous (dangerous) plate voltages.

I have very lmiited multi-room experience - a single experience: four zones, using a Russound impedence matching autoformer / volume control. Be aware that impedence matching devices may need to have jumpers or other physical settings changed to match the impedence of the speakers: On the one and only job I did the speakers were 4 ohm despite their documentation saying they were 8 ohm, resulting in a thoroughly smoked zone controller and Yamaha 2channel receiver.

I don't remember reading the model number of this SC amp, but it looks like an ASR-120. Tom Bavis (IIRC) maintains the Made In Rochester site for SC stuff, and has the schematics and a bunch of sales literature for a BUNCH of Made In Rochester (NY) stuff: http://www.audiophool.cjb.net/MadeInRoch.html I have the SE little brother to this PP unit, the ASR110. Thinking about turning it into a 120 if I have the sockets for it as my next project. Needless to say, I'm reading this thread with great interest!

I found http://www.popsike.com/ some time ago... purports to be the same kind of thing. Updated periodically, not in real-time, so it may not show some too-hot-to-touch auction that happened in the recent past, but it's IS updated. From their 'News' panel: 2011-05-16 120'000 auctions added 2011-03-19 100'000 auctions added 2011-01-23 90'000 auctions added 2010-11-28 100'000 auctions added 2010-10-04 120'000 auctions added 2010-08-07 100'000 auctions added

Not strange... physics. Paraphrasing my learning (here and elsewhere) and My Understanding (take THAT with a pound of salt! ) The air space provides a very specific spring force that works in conjuction with (and contrary to) the force of the woofer being pulled back into the box. The "air-spring" counterforce helps accellerate the woofer cone outward thereby increasing efficiency. Even "open" speaker enclosures (thinking ported speakers here) have tuned ports rather than simple open baffles, the length, diameter, and shape of the port providing different amounts of pushback to the woofer. Passive Radiator designs are no different, AFAIK. I've seen talk of tuning passives by adding mass to the passive cone to accomodate different active woofers. Different low frequency drivers have different "Thiel-Small" parameters, which one can plug into WinISD or similar DIY Speaker Design software to try to come to an optimum efficiency and package size. All design is a collection of compromise... efficiency and frequency response versus size is probably the biggest compromise in speaker design; There is, of course a LOT of subtlty... Internal bracing and blanketing to supress vibration (especially harmonic vibration,) material selection for weight/vibration/cost, etc. The end goal of design compromise is, of course, to create a product that performs well enough to inspire people to buy it, at a price point that inspires people to buy it.

No sibilance on my Speakerlab-Ks, but they've been pretty substantially upgraded: ST350B 'babycheeks' tweeters and modded A4500 networks, the mods to flatten the hotspot on the ST350Bs around 9k (IIRC.) The mod is an added R/C/H segment straight out of the documentation from the tweets. These are fronted by NAD114 and PE2200, with vinyl, CD, and HTPC (FLAC through an Asus Xonar card.) No harshness or fatigue in any way, altho a friend with a more sophisticated ear is convincend he hears "something" amiss, and we're working on finding whatever 'it' is. []

Perhaps take a digital photo of the plate before grinding the numbers off, then carefully obfuscate the numbers to demonstrate that there was a SSN there that you removed? Include the carefully redacted photo with the sale?

450 Sterling is a GREAT price. Heck, I'd love to find a pair for $731.75USD on this side of the pond! Congratulations, and welcome to the club. --Edit: I believe the serial numbers should be stamped or embossed in the wood at the back, top edge of the cabinet.

Some updates for you, JB!

My favorite method is to use a photo-hosting service, such as tinypic, then copy and paste the resulting "IMG tag URL" into a post here. Tinypic also resizes for you (shoot for 640x480 or 800x600 in the Klipsch forums) and you can also post multiple pictures into one post with multiple "IMG tag" URLs.

NAD T763 HTR driving Quartets for a year, followed by LaScalas for the last four or so sounded great in my theater. NAD 114 pre-amp fronting a NAD2240PE amp also sound wonderful with Cornwalls (six months or so) followed by highly modified Speakerlab-Ks (for the last 18 months or more.) Solid State and very high efficiency can be tiring... NAD+Klipsch Herritage is a combo listening to which I've never suffered.

Another potentially spendy solution, but strong as eh eee double-hockysticks: http://8020.net/ 8020 bills themselves as "the industrial erector set" and they are more handy than you could possibly believe... check out the examples on their web site. This stuff is basically extruded aluminum of various cross sections, with slide- and fixed-fasteners for hard angle mounting, hinging, connecting extrusion to extrusion, sliding interfaces, doors, you name it. A cross section with slide nuts of appropriate size and thread, along with some hanging mounts, and you're there.

Two thoughts... 1) Pro amps with fans may not be a problem (check the literature!) but passive amps with cooling vents would most likely be very unhappy running perpendicular to their intended airflow. There are a bunch of spiffy wall mount 19" EIA rack solutions available... Not cheap, but one I've installed recently: http://www.blackbox.com/Store/Detail.aspx/Wallmount-Cabinet-36-H-20U-x-20-D-Black/RM433A%C4%82R2 Of course, there are open racks that are wall mount and FAR cheaper than that BlackBox solution.
