  1. Hello all, first post so bear with me. I've been looking to restore a pair of AR speakers and have realized that the previously recommended Wichelt 18 count lambswool linen is no longer being produced as of summer 2021. I'm sure this is a major disappointment to many as this was the go-to cloth for restorations for many years. I figured I would start this thread to compile different ideas in one location regarding the most accurate and authentic cloth. I'm sure that there are plenty of cloths out there that are fine and look good, but I'm looking for the cloth that most closely resembles what was on the speaker when it left the factory. So far, I've seen a few different options as follows: Wichelt 20 count lambswool linen: seems to be intermittently available on the auction site but is noticeably more expensive than the previous 18 count Wichelt 28 count lambswool linen: still available from 123Stitch (https://www.123stitch.com/item/Wichelt-28-Ct-Lambswool-Linen-Needlework-Fabric-27x36/76-135X) though the thread count is higher than the 18-20 thread count that AR used on their original cloth Bleached IL041: recommended by @zcon67 and available at https://fabrics-store.com/fabrics/linen-fabric-IL041-bleached-middle. 19-20 thread count according to him Open Weave Medium Weight Natural Linen – Y0400NT036: suggested by @genek and available at Ulster Linen (https://ulsterlinen.com/shop/linen-use/scrim-linen/medium-weight-natural-linen-fabric-y0400nt036/). The thread count and slubbing appear correct but the color may be too tan? Does anybody have any other ideas on a suitable replacement? If so, share below, especially if you have the cloth attached to frames. Thanks
  2. So, I was at Brimfield yesterday and found a Twenty One in not-bad-at-all condition (excellent cosmetics on the front panel, grille cloth, dial and knobs, veneer quite restorable), so for $40 I thought it was a good pickup. I was told it doesn't power up, and by gum it doesn't (the fuse doesn't look blown, though), so I'll get to work on it for my late summer project! I think JKent is quite experienced with the 21, but if anyone has some tips of the "low-hanging fruit" variety, feel free to share.
  3. These speakers were given to me by a friend of mine at church who had them in the back of his truck destined for Goodwill. The cabinets were fairly rough and the grille fabric had been replaced but everything else was original. I had never restored a set of speakers before but thanks to the encouragement of Roy, Glenn, Kent and others on this site, I have spent the last 6 weeks restoring them and am very happy with how they turned out. Here are a few of the details: Year: 1963-4 Make: Acoustic Research Model: AR-3 Serial #s: C21604 & C21611 Restoration summary: - Original dual 24uF and 6uF paper capacitor replaced with new Solen 24uF 400V and Dayton Audio 6.2uF 250V Precision Audio Capacitors from Parts Express - Original 16 Ohm / 25 Watt wire-wound potentiometers were corroded beyond repair and were replaced with modern reproduction wire-wound potentiometers of the same size and specifications from captainfantastic07 on eBay. - Cabinets sanded and hand-rubbed with Watco Danish Oil (Dark Walnut) and finished with four coats of Minwax satin polyurethane. - Woofer perimeter and bolt holes resealed with speaker sealing caulk from Parts Express - Original plastic speaker grill frames replaced with more durable 1/4" Masonite for easier installation and removal. - Masonite speaker grille frames spray painted flat black before wrapping with fabric to prevent frame being seen through fabric. - Reproduction speaker grille saran material from Q-Components in Canada. - 3M automotive trim adhesive tape followed by ¼” heavy duty staples to prevent slipping of material or fraying of fabric edges - Reproduction “AR Inc” and "3" pin from jKent Attached are a few pictures so you can see before and after and some of the steps along the way. I plan on enjoying them for a while and then will probably try selling them locally before putting on eBay to avoid the hassle and potential damage associated with shipping. Thank you to Roy, Glenn and Kent for all of your input and for the wealth of information everyone else has contributed to this site! If you have any questions or comments, please let me know! Thanks, Steve
  4. I will start this off by saying although I've dug through many threads about restoring, recapping, refoaming, repotting these speakers I am pretty much a total newbie to actually doing the things. The other day I came across some pretty decent looking AR-5s on the local marketplace. Took em home, took off the grills, and the foam is gone. Alright, I can handle that. Pulled the woofers. One measures 6 ohm, which is fine I think, and the other, open. Not great! So I dig out the rockwool and look at the crossovers: One appears to be fine, the other looks like where the resistor wire (?) is on the little board has basically burnt to a crisp including a bit of the surrounding insulation. I didn't remember to make not of which speaker came out of which cabinet but am I right to guess that the blown woofer probably came out of the cabinet with the fried resistor? My questions are: 1. What might have happened here and what kind of damage may this have caused to the blown woofer, if in fact it came out of the same cabinet? Or are these things unrelated? 2. What might it cost to get this blown woofer fixed? I'm looking around and guessing I won't be able to find the right drop in part any time soon. I'm not far from Millersound, I'm guessing that is the best place to go for a repair. Thoughts? Next move is going to be clean up the pots (or bypass) to see if the mids and tweets are functional. Then caps after that. Thanks for any help
  5. Well i blew a tweeter a couple days back. So I'm gonna need to.find some suitable replacements. I'm hoping that one f ya'll can give me some other models that have a tweeter that will be a match to the vr40. Obviously I can't get any orignal VR40 pieces, unless someone here has a couple they would part with. Thank for reading my post.
  6. This is the first topic I create as a new member of this great community. I've been an audio fan since I was 15 years old, and have been experimenting different systems until now. (I'm 41) I love classical and jazz music, specially in Vinyl or analog formats. So you can figure that there is no coincidence for me to be here writing about AR3 Loudspeakers. I came across this particular model because it delivers what I look in a recorded musical performance. My search stopped some 12 years ago when I bought a pair of rare Hegeman model 1 loudspeakers, that really filled me thanks to their special ability to create a realistic concert hall effect, with great presence and very deep bass response. But it was'n until I got a pair of Advent 5012 that I realize that there is a new world below 40 hz!! These simple speakers got my attention. I read a lot about east coast loudspeakers but untill then, never had the chance to test a pair in my own system. So my obvious step was to think what loudspeaker would give that ammount of bass and presence with more accuracy in the mid and high region. That's when I started to think about giving AR3's a chance. I took some time for me to decide, because I had a pair of AR10pi in the past, but the woofers were incorrectly repaired, with very stiff spiders and surrounds. So I bought a pair of OEM AR woofers from simply speakers. But for my surprise, those resulted to be as hard as the repaired ones I had. So I never discovered the real low end of this model and ended selling them. Few months ago, I found a pair of AR3 in hands of a louddpeaker tech, wo had them sitting for 20 years literally collecting dust without the grilles in a very dirty environment, so the drivers suffered, the tweeters rubber suspension dots failed, and domes were pushed out breaking the fragile voice coils. Midranges are not working, they collected excess of dust that came in the voice coil gap. Woofers are physically ok, but only one works. cabinets are a little raw but still un good shape. So my questions are: I want to restore them and make them work the best as possible soon. Where I live, original parts are very hard to find. I think I could start restoring the woofers and get oem mids and tweeters that are available until I can find mint condition original drivers on Ebay. Mids and tweeters are very hard to repair to get them to their original shape, so would you recommend to use the oem AR mids that Simply Speakers offer? Are those suitable for AR3? (they sell them as AR3a's replacement.) For The tweeters I'm thinking about getting a pair of Hivi's. I will aporeciate your comments and reccomendations. Best, Howard
