  1. Ohio! Ohio! The best AR speakers come from Ohio. Or is that Chicago? Man I would be like a kid on Christmas Eve night. Hope to see you at Midwest Audiofest in July. This time I wont miss you. Good Luck.
  2. The next step is to apply some of Roy's goo to the cloth surrounds. I began brushing and gently wiping the surround and noticed the woofer moving around. I appears the masonite ring has come unglued and detached. How could I have missed this? Close inspection of the other woofer reveals the same condition. I do not want to remove the woofers and definitely do not want to remove the dust caps to align the voice coils. I decided to carefully scrape the old glue off and align the voice coil with a 30hz test tone. Of course I used Aleene's Tacky (the glue of the gods) Notice the 1/2 in nuts used to weigh down the ring, but that was not really needed as you can keep applying pressure as the glue sets. Also I like how you can take the midrange and tweeter out of circuit with the rear jumper. The next step was to spruce up the cabinets a bit. They are really in very nice shape with just a few superficial scratches.First I used a razor blade scraper and goo gone to carefully remove the remnants of the felt pads. I then used Scotts Wood Wash (sold under the Liquid Gold brand) and you wouldn't believe the dirt I got out of the veneer. Wiped on and wiped off some Howard's Walnut Restore-a-Finish and was quite pleased with the results. Lukecat is making me a believer in this, although I am not ready to use it as a stain. Finished with some Howard's feed n wax. Roy's surround sealer stays sticky for a long time. Try not to touch it. I have no place to display these without pulling down my 5's or 3a's so they are temporarily on the fireplace hearth to evaluate them. I used the Scott R77S that they were probably accustomed to initially, but then switched to a SX-1250 and lastly to a Adcom GFA555II. They do sound really good. I still prefer my 5's and 3a's. Probably these were originally used with tubes and I do have Scott 299c ii can try. Unfortunately today is their last day, for I am going to Home Depot to get boxes and styrofoam to pack them away. I will probably let them go, because I have another pair in Korina finish that I will hold on to. I tried to restore them to keep as close to original as possible.
  3. Thought I should finalize this thread and report on the AR2a's which have been completed for a week and have about 40 hours of listening time. The woofers were really sealed in and I had to take a razor knife and cut around them to gently pry them out. The backs of the magnets were covered with a fine dust which I determined to be fiberglass. The crossovers looked just as they should with a 4uf and 6uf wax cap block. The 6uf section tested 7.6 and 7.75 respectively. The 4uf section read 5.1 and 5.89. The coil read 1.278mh and 1.318 each. I decided to replace the with new polypropylene caps which I chose the two most closely matching pairs from a group of eight each. The pots were in relatively good condition from what I had seen before. They were a slightly different design incorporating a different wiper with a small spring. I would guess these are from 1960-61 time frame. Here are photos both pairs with the left cleaned and the right uncleaned. I used a Dremel with a brass brush and coated them with DeoxIT G5 to treat the metal. New caps installed with new 16 gauge OFC copper wire. I left the original cap block in place. Fiberglass back in place. New caulking strips installed. These are the ones from Parts Express and are almost identical to what AR used originally. Notice the 6 in. leads soldered to the woofer and wire nutted to the original leads. This is something I got from KLH and doubt if AR ever did this. Also notice the painters tape with the tic marks to help me line up the screw holes when reinstalling the woofer. Everything is going swimmingly. It's like I had done this before. Then the hickup.
  4. I used my Dremel to cut a spacer ring to use a smaller basket AR2ax woofer in a larger opening. Used 3M double sided tape to hold the 1/8 in. hardboard in place on a scrap piece of plywood while cutting. The secret is not to let your material move around while cutting. I have also cut woofer openings in new speaker grills.
  5. I have one of these gizmos and it seems to very easy to use. http://www.homedepot.com/p/Dremel-Circle-Cutter-Attachment-3-4-in-to-12-in-Diameter-678-01/202713389?cm_mmc=Shopping|THD|google|&mid=sfHqDAqWe|dc_mtid_8903tb925190_pcri
  6. Those have to be early examples. Do the back plates look like this? I too have three sets of these. This set with 69XXX serial numbers have been dated to 1963. They have been re capped and resealed by me. Not a easy feat having to perform all work from the back. What a great sound coming from these. There is just something right about the sixes.
  7. I have been following this thread with much interest. I admire your attempt to bring the original veneer back from its current state. If these were my cabinets I would tend to agree somewhat with Glitch. You have solid originals with the proper documentation on the back. My thought would be re veneer them with some nice quartersawn teak veneer. Done right they would be some very collectable 3's. Just my opinion. Whatever you do will more than likely look good. Oh and by the way, what ever became of the 1967 3a cabinets?
  8. Those look a lot like my domestic AR38s speakers. The speakers in question are no longer available. I am still convinced they are some type of hybrid ADD speakers. They have the same dimensions as the AR 11,12 and 14 cabinets. The same thin front reveal. Same woofer gasket and fabric dust cap. A tweeter from that series and terminal plate only used in ADD speakers. I guess we will never know unless the new owner comes forward with more information.
  9. Currently listed on the auction site are a pair of AR speakers that the seller cannot identify. I can't recall any models quite like these. Are they some kind of custom one of a kind user fabrication or could they be some kind of factory prototype? I am pretty sure these are not AR 38's due to the size, tweeter model and placement and also the terminal plate. Here is the complete listing. http://www.ebay.com/itm/262934211929?_trksid=p2055119.m1438.l2649&ssPageName=STRK%3AMEBIDX%3AIT From the cabinet dimensions given I would put them as AR 14's. The cabinet lacks the groove in the veneer around the front and also the lower trim panel. The woofer appears to be correct, but that 1 3/8 tweeter belongs in the AR 18 and 25, not in a AR 14. The grill is definitely aftermarket. If theses were originally AR 14's they would have to have new baffles because of the cutout for the 1 in. dome tweeter. Any thoughts on what these are or could of been originally?
  10. My first thought would be to swap the left speaker with the right and see if the problem speaker is still present. After eliminating the wires and amplifier as a cause deffinantly look at the solder connections and speaker connectors. Those spring loaded clips are espically problematic. New 6uf capucators are probably in order. Caps can fail open or closed or just go out of spec. Keep eliminating things till you find the culprit. You could swap woofers and see what happens. Hope that is not the problem.
  11. Here is the Irish tea linen on my AR4X's. One piece will do both speakers. I bleached it slightly to lighten it up a bit. You can see the left over piece. Did not notice much shrinkage. Dried it between bath towels then ironed with a little spray starch. Not bad for five dollars. The Wichelt 18 ct. lambswool is nicer stuff, but more expensive.
  12. Michale's has some 28 count Irish Tea Linen at a good price, espically if you use the 40% off coupon. I soaked my cloth in some diluted bleach water and made it even lighter.
  13. Hooked the AR2a's up to a little Lepai 2020A+amp today and got sound from all six drivers. Pots will definitely need cleaned for they had several drop outs. Ordered new caps from Madisound last week and they are already here. Time to remove the grills. There were twenty small brass colored staples to be removed. Used a small jewelers flat blade screwdriver and 8 oz. hammer till I could grab them with needlenose pliers. Was careful to avoid snagging the grill cloth. Use some plastic pry bars, the kind used in car stereo installation to loosen the grills. It seems there is a channel the grill fits into and it takes some finesse to get them out. I finally got the grill out with only one small crack in the masonite. Will be extra careful with the other. And there were the drivers. First time in the daylight in over 50 years. I have to go into work tomorrow, but Wednesday I will get the pots out and cleaned. One more thought. I have some built in and freestanding bookcases, but nothing that these will fit into. I have to give some thought on how I am going to display them. Maybe I will just lay these across some other speakers.
  14. Thats a good point on the horizontal orientation of these speakers. In fact if you look closely you can see the remnants of some felt pads on the long side. The badge is installed with a small screw on the back, so they can be rotated. Do not have the stick pin "a" badge. I ordered a set for my first set from Kent since they were missing all badges. These are definitely walnut veneer and I doubt they need much done to them. My first set are the rare Korina veneer and are labeled that way. As far as the bonus Scott R77S receiver, the picture I posted it not entirely accurate. The display is green and it does have the Maynard MA Powdermill Road address on the back. One thing I noticed is that does not seem to have a protection circuit. The DC offset on both channels is below 7ma, which is extraordinary. I have a Bluetooth adapter hooked up to the aux and streaming music to some restored AR 25's and I don't think I have heard them sound so good. Have yet to hook these AR2a speakers up.
  15. Looking at those pine AR3a's makes me want to share this short story. My middle son lives in Chicago and works downtown on Michigan Avenue. A few weeks ago he had a coworker and his wife over for dinner and he commented on the KLH model 23's I had given him. He said he had some old speakers stored in his garage that were his grandfathers. He didn't think they were KLH's though. My son told him his father is into old speakers and may be interested in them. A week or so later my son stopped by and sent me four phone pictures of them. They appeared to be really nice AR2a's and looked very much original. I didn't want to offend his coworker with a low offer, so I decided to offer $250.00 to start with. He accepted the offer. Last weekend my son was down for a birthday party and brought me the speakers. They were way nicer than I ever could have imagined. I don't think they had ever been touched. I haven't hooked the up yet but will soon. Now for the icing on the cake. When my son stopped by to pick them up the guy said he also had his grandpa's old receiver and wanted to get rid of it. It was a old Scott which they both had never heard of and a quick google search came up with little. My son ask what he wanted for it and they agreed on $50.00. I knew nothing about it till he showed up with the speakers. Turns out it is a Scott R77S and in like new shape. Made in the USA in the very early 70's. I can find nothing wrong with it. Not a scratch, light out, no noise or anything. This guy's grandfather must of taken excellent care of his gear. I let my son know I was happy and gave him a nice finders fee.
