  1. 3a, LST & LST-2 tweeters

    CJVx Very nice gent. Those Altec tube monoblocks were rated @ 100w. Both sets of LST's sounded fabulous! Glenn
  2. 3a, LST & LST-2 tweeters

    Chris has been working with Roy and Larry at vintage-ar. on these. I most definitely will! Several Northern NJ Akers attended. The meet was at the Blue Mountain Reservation Lodge in Peekskill, NY. I'd love to meet more audio maniacs like myself! Also, some of us are planning to meet at the NY Audio Show at the Park Lane Hotel. I attended last year and it was great to see all super high end gear and hang with some AK members. So lets see how many NY metro locals can meet up! Here's the link. Glenn https://www.chestergroup.org/newyorkaudioshow/2017
  3. This past weekend we had an AK NY metro gathering. Chris who is restoring the 3a & LST tweeters brought both of his pairs of LST's, the AR Wall!. All I can say is they sounded fabulous and looked great! What a godsend for all who have old dead tweeters! You can keep those treasured speakers original drivers! When I restored my LST-2's a couple years ago, no one could fix dead tweeters, which all six of mine were dead. Roy said they were basically paper weights, so I chucked them! Did the HiVi swap and crossover mods Roy recommended to do, and I'm very happy with how they sound. I usually don't do things like that, but I saw no point keeping them to collect dust on a shelf. Well, fast forward a couple years and now of course wish I had kept to my old never throw anything out days! Chris said they most likely could have been restored if I still had them. So basically, this is a plug for Chris's excellent work on these. Amazingly, he also reproduces the often crushed black paper domes! They looked perfect! Glenn
  4. The sofa is the waiting area while your piece gets fixed!
  5. Well, it's really up to you, right? Buy them, and sell some others to cover the cost, buy them and don't sell any other speakers or don't buy them. 2,600 is not cheap!
  6. Hi Tom, Your 3 looks very good for so early a model. You're very lucky to have such an early example. Glenn
  7. ADS 910

    The 910's originally were designed as studio monitors. They are efficient, put out huge sound. I doubt you will need a second set of speakers with the 910's. As David noted, use them by themselves first. You'll see! Do you have the factory stands? They raise them 7 inches even though the owners manual states 10 inches. Raising them makes a big difference and improvement in sound. Glenn
  8. Help Identifying AR3? AR3a

    The original grill frames were plastic, and would bow out so you could remove or insert the top and bottom so they would slide into the slot. Later 3a grills just fit flush and the frame molding had flat inner edges. I recently restored my 2nd set of 3's, and made new grill frames using 1/4 inch MDF. They are cut to size to fit flush with the molding edges, and the Saran grill cloth adds enough added thickness to make them fit nice and snug, but can be removed easily if needed. Glenn
  9. Do you have a low serial number pair?
  10. any tips for Walnut touch-up?

    I believe you are correct regarding a lacquer finish. MayI suggest getting a can of gloss lacquer, and using a small artists brush and touching up the areas that need attention. Try a small area first. Lacquer stinks, so I'd say do this in the garage or outside.
  11. Second pair of ARs! - AR 4x

    Very nice! Terrific they are from the original owners! They look very similar to my 4x's as well. My serial numbers are 376790 & 376794, also purchased from the original owners son. Mine are all original and sound terrific! I did apply a very thin coat of Roy's sealer to the surrounds, which made a noticeable improvement in the bass output. As ra. ra stated, they breath through the dust cap.
  12. Another Fine Pair

    I was thinking the same thing! Another great find David! Look forward to seeing them opened up once you get started on them. Cheers, Glenn
  13. Might get a few treasures soon...

    Looking forward to what treasure is revealed!
  14. Couldn't resist! Now what? Franken-3a

    Hi Geoff, Definitely try to remove the pieces on the plywood with some heat to put back in place on the cab. Harvesting veneer from the 4 cabs is a good move, vintage veneer will be a much better color match when refinishing. That grain pattern is beautiful and unusual, si there lies the challenge. Some artful use of some dark walnut oil or stain should help with those darker areas. Glenn Glenn
