    Vintage AR2a with vinyl finish (year)?

    Ugh... Laminate.... Baaahhhh I acquired a pair of KLH 6 many years ago that had the nasty woodgrain vinyl covering. I tried to heatgun it off but it didn't want to leave it's moorings. I ended up filling the crunched corners using wood putty, washed the vinyl with acetone, applied adhesive back cherry veneer for the sides and hot melt cherry banding for the front. It actually turned out pretty nicely.

    Calling Frank Marsi

    Frank Says; I find for home stereo use, 10 inch woofers try to satisfy but, just don’t have the where with-all, 8 inch woofers are simply inadequate, and 15 inch woofers just too lumbering and slow. I do agree about the 12" being optimal. My 3a pair has the cat's meow in the sub 70 hz range, whereas all the variants of the 2 series just don't thump adequately. Frank Says; Although, I’ve lately been getting back into playing my bass guitar again, I first had to have my Bassman amp refurbished. It has two 15 inch speakers and still puts out well enough. I also find it amazing how playing guitar has been elevated to new heights by the newer generations and styles of playing, especially for me to see since I use to play 45 years ago. The amplifier was slightly modified from 50 watts to 70 and seems to put-out a touch more. In the guitar amp-world, tubes have their place however, replacing tubes is costly, as I shelled-out recently but, I always knew this is the cost of admission. I too have a Bassman, mine is a 1978 silverface Bassman 70. I have had it since the early 80's I recently replaced every electrolytic cap in it, it brought back the oomph and lost the Mmmmmmm. I didn't use the Fender cabinet for gigging though. It was connected to a sideways stacked pair of Acoustic Control Corp cabinets. A 360 (1 x 18") folded horn bottom with a 250 (2 x 15") on top Those were a bear to schlep down greasy staircases into places I'd play at but wouldn't be seen at otherwise. They are still at the drummer's house. Now it plays through a 1 x 18" sealed box cabinet, plenty for small hall or casual jams.
  3. Just saw this on the Audiokarma site; http://audiokarma.org/forums/index.php?threads/acoustic-research-ar-94sx-tower-speakers-need-work.832391/ It's on their bartertown section so you need to be a member to view it, but if someone needs I could message the donor on your behalf.... Lou UPDATE: The individual who was so generously giving these away informed me that they have been adopted and are no longer available.

    How Long Have You Owned AR Speakers?

    My first AR speakers, a pair of late '50's AR-2, were acquired in 1972 when I was a sophomore in high school. I have since had at least one pair of AR in the stable, usually many more, although now I'm down to one pair of AR-2X, one pair of AR-2ax and one pair of AR-3a. All of my AR's were first gen speaks.

    Good workout for the 3A

    I really like the small footprint of the Dynaco preamps. The Crown seemed like a really big cabinet for a tiny board, but I guess bigger must be better otherwise who would have bought all the rack systems in the 80's or the console entertainment centers before that?

    And I looked up Ballykissangel. That's just the sort of BBC series my sweetie is fond of. Aargh! DVD.com only has Series three through six. Looks like someone never returned one and two. And there isn't a copy of either in any of the nearby libraries. Oh well, Skunked again. I did see the updatemydynaco stuff for sale on the auction site as well as his page after you mentioned it. After having replaced all the goodies BUT the transformer I'm sorta reluctant to bug the guy with my pipsqueak of a problem. If the placement of the trans outside the case doesn't do it, I'll review the circuit and try to figure out what I may have done wrong. Wouldn't be the first time. After replacing almost all the passives, the thing really does sound good ( other than the hissy phono preamp, which he has a kit for ) But I digress, Another nice display of the 3a's prowess I was listening to is Big Big Train's 2016 album "Folklore" When I listen to it on the 2a, the 2ax or the KLH 6 systems it's just missing the overwhelming punch of the 3a's ( the above mentioned are all I have connected now )
  7. Yep. the " sleek horizontal credenza amidst a room of modern furnishings but then flanked by a couple of stunted classical Doric columns " was the design motif change I had in mind when I dragged these examples of columns from the Greek Temple Of The Vertically Challenged home one day. Our design aesthetic has always swayed more towards the late Victorian, so Mid Century Modern ala Herman Miller was about as jarring as possible. It was quickly nixed. These sat in the workroom for about two years and at the time I mentioned it here I also put a listing on the auction site. I was PM'd within a couple hours and the deal was already done last night. And yes, the drivers were something to behold... The return of Monster Magnet describes those woofers to a T So anyway, they are indeed gone to someone who can fit them into their decor. Best regards, Lou

    Good workout for the 3A

    When I got mine it was in pretty deplorable condition. It was covered in nicotine goo and was pretty scratched up. I did replace all the electrolytic and the tantalum caps. I did a cosmetic redo, but where it sits nobody will ever know. That power supply was absolutely killer for an amplifier of "only" 75 per side. It handles the 3a load all night long without a complaint. When I got it, it was paired with a PAT-4. I recapped that and replaced all the carbon comp resistors too but was never able to rid it of that vanishingly small 60 hz hummmmmm. It was SO faint no one else noticed it, but I did and it just bugged me to no end. One of these days, I'll relocate the power supply out of the case to verify whether my suspicion of EMF pickup from the transformer is correct.
  9. Hey all, If anyone in the Chicago area wants a pair of 1967 Empire Grenadier 8000 speakers, please let me know. I'm pretty sure they were '67, since I think that was the only year they were offered in all melamine woodgrain laminate including the tops. (not marble) They're functional, the tweeter domes were the victim of kiddie fingers and so will need to be pulled back out properly. The crossovers are original and so the caps should be replaced. The cloth suspension 12" woofers are original and so the cloth should be treated to restore pliability. I got them a while ago and the mid century modern look just doesn't gel with our interior motif. If someone wants 'em just make an offer. Anything reasonable accepted! Best regards, Lou
  10. As I have mentioned previously, My 3a's are doing duty in the family room ( or as the 1928 architect's plans said, "Billard Room" ). In this setup, they're powered by a Carver C-3 preamp and a Dynaco ST-150. Last night, We were watching an Irish film titled Pilgrimage. The soundtrack was exceptionally well recorded and the drums were enough to stir the Celtic heart of anyone who hears it. So sad that most folks who may watch this would be hearing it through the tiny reproducers mounted in their TV's.
  11. I have been exposed to industry shill rags ever since I was first lured into this hobby. That was when Julian Hirsch held sway at Stereo Review in the early 70's. I recall many reviewers gushing about gear that sounded like dung to my teenaged ears ( which I believe were more attuned to musical nuances than my old tin auditory receptors are now ).... Any time there is a pot 'o gold in sight the charlatans will rush to behold it's beauty. As I see it, the only ones less deserving of one's trust in regards to opinions of product are the schmucks inhabiting the audio showrooms. OK, my soapbox ride just ran out of time for this dime. I think I can safely state that anyone who has found their way to this site has a pretty darn good sense of musical reproduction, colored or not.
  12. Hmmmmm.... Now I gotta do is come across some JBL 123A’s! The only reason I didn’t particularly like the TDC-1028 drivers ( even with the addition of the inductor ) was the bass had that constricted quality that the AR woofs don’t. But appreciation of sonic qualities is of course a personal preference thing and maybe someone might like ‘em more than I did. Lou
  13. Yep, time was that the classic AR driver components seemed to be dime a dozen. At one point, I had a pirate stash of most of the goodies from the various 10" classic iterations. As it was, I ended up using or mostly giving away items which are now commanding relatively steep prices. Oh well, you live and learn. Say, are you the Craig that I chatted with occasionally on the H.H. Scott listserv?

    KLH Model Six Restore

    Hello Willcee, To echo Kent's reply, do not use calk or anything but the butyl wondergoo described above. I had used a product that had been described as being good for the task by someone on another forum and much to my dismay it was the worst! The surrounds were sealed, but as time went by they became quite stiff. I described the removal of the product in another post earlier. It worked, but as Kent said, don't use anything but Roy's stuff. It works.
  15. In August of last year in the AR forum I described using shoe goo for a sealant material. As was suggested, it was indeed not exactly the best goop for the purpose. While it did seem quite pliant when first applied, the stuff did stiffen as time passed. I had used it not only on a pair of AR-2ax but also on my KLH 6. The surrounds had stiffened to the point that there wasn’t much response below 90 hz or so. When looking at the shoe goo manufacturers website, they did list a number of solvents which would temporarily resoften the stuff. One of them was listed as being gasoline. I chose to use it since MEK was likely to dissolve the glue holding the cloth to the frame and the cone. It did work, and quite well. Softened and scraped right off. After allowing it to dry adequately, there was just enough remaining in the fabric to allow for sealing. I was left with a pair of woofs that actually were now quite floppy again. Just to see whether they would stiffen up again from the little amount remaining in the cloth, I chose to exercise them for a while. I ran a couple watts into them at 7 hz in free air for about ten hours. They remained nice and floppy. I reinstalled them and they once again are properly working, with a resonant hump measured at about 43 hz. But that’s in the workroom with an sm-57 on axis at about two feet and so of questionable accuracy. They sound like what I expected, so oil wells that end well.
