  1. Roy, it is one of the early versions. But what about that transformer? It almost looks a little like a "special" AR-6. Well, you were the only one at this point to mention anything about it, but it was one of several AR-6s specially built by AR in Holland for the old Royal Opera House in Copenhagen. I think when they were building the new $500 million opera house or before, they took out all of the old stuff, but I'm not sure of the actual history. Klause was on hand to get many of the older ARs when they were removed several years back. Through a little woofer "horse trad
  2. Do you AR recognize this AR-6 and anything different about it? --Tom Tyson
  3. I've done just that with many drawings, but you may not realize the scope of the number of drawings that would have to be done this way. I've used my Canon 5D-MkIII to take pictures of several drawings with great results -- and this camera is very precise with high resolution -- but it is very cumbersome and time-consuming to mount a drawing on the wall or tape each drawing to a drafting table with the camera on a tripod above (which is the way I've done it most of the time). A large-format scanner is much faster will give much better results because there is little lens distortion or light
  4. dna, thanks for your inquiry. I am working on the book project, but it goes slowly considering many other responsibilities, so there is still a way to go on it. I was a bit premature in "presenting" the project so early; I should have waited a bit later, but I'll get there. The Administrator posted this "separate" topic before I was ready, so this is where we are at this point. As for printing, I prefer to have it printed by a publisher, but we'll have to wait to see how that works. One has to have an agent to get a publisher. As for the "AR Archives." There are around 15 5-dr
  5. Will 200044 mid ranges work in the ar 9  I just got a pair and that’s what’s in them they also have been re coned with original magnets but cloth surrounds on lower mids  sound great but was wondering the difference between 200028 midrange. Thanks Ken 

  6. The pictures are not clear, but I'm pretty confident that the cabinets are walnut. C 4747 were built mid-1960, I think.
  7. Extrapolating the dates of other LSTs; e.g., LST No. 00367 was built in August, 1972 and No. 00609 was built in December 1972, and AR was building around 60 per month during this period, on average. Therefore, I think 00775, an early style LST, was built in Cambridge around February 1973, just before AR moved from Cambridge to Norwood. The L-1672 is the tag publication number, I believe, but not the build number. --Tom Tyson
  8. Greetings, Adriano! I love your pictures of your family's AR-2s. They were almost perfectly placed on the shelf, and the sound would definitely have been very clean and smooth! An early picture of Ann-Margret Olsson adjacent to her left-channel AR-2ax speakers, somewhere out in Hollywood in the late 1970s. Ann-Margret and her husband Roger Smith were music-lovers, and Ann-Margret was an accomplished singer and dancer, not to mention expert in high-fidelity sound reproduction! This extraordinary actress could ride a motorcycle well, too! --Tom Tyson
  9. Hi Tom, thanks for your comment. As I would like to have you in Buenos Aires to hear more about these stories, as you can imagine they never arrived in Argentina, I appreciate sharing them with me.
    I tell you that the numbers are 31169/31170 and the year is 1958. The boxes are like new. Imagine if they were from the US embassy, and then had only one owner, they were very well taken care of.
    Unfortunately I sent the two woofer for repair, I prefer that they be measured with the same graduation. I send you warm greetings from Buenos Aires, and if you come one day, I would like to receive you. Hug.

      Hola, y muchas gracias por tu mensaje y palabras amables! ¡Disfruté mucho la historia de sus altavoces AR-2 y su gran herencia! ¡Muchas gracias! Saludos cordiales, y si algún día llego a ese hermoso país, te daré una "campana". --Tomás Tyson

      you will be welcome

  10. Thanks for that update. I've been to that house and actually stayed over a weekend as a guest of the Villchur family some time ago. It is a great house up on a hill! Price came down a little, but it still did well! Beautiful land!
  11. Please try this link. The first one apparently developed an issue. https://www.indiegogo.com/projects/edgar-villchur-the-american-inventor?utm_medium=email&utm_source=lifecycle&fbclid=IwAR0dCjwtc216lHjol9gNnTE2PN0ow4Epa6whX3gQDfqjdKq_1-LQIZn-q2o#/
  12. Hello Friend of Acoustic Research: A documentary filmmaker from New York -- living in the same town as and acquainted with Edgar Villchur -- is making a documentary film on the life of Edgar Villchur. This film producer is Cambiz Khosravi, a well-known documentary producer, and he is well on the way with his project, "Edgar Villchur: The American Inventor." I've helped him quite a bit, and I think the documentary production will be very nice and a great tribute to Edgar Villchur and Acoustic Research. Mr. Khosravi does need any help he can get to cover the cost of the "production stage
  13. It is rare for the original AR-2 cloth surrounds go bad in most cases, and it is best not to replace with urethane-foam, as this was not original. Foam surround may possibly change the free-air resonance slightly as well. Test the woofer first for air leaks, and if the woofer isn't bad, don't modify it. Leave it alone, but be sure that the cabinet does not have air leaks (use a stethoscope and 30Hz to listen for air leaks). This speaker also has the WWII-surplus, mil-spec (Army-Navy) oil-filled capacitors and the high-quality A-B level control. Therefore, it is rare for the crossover
  14. Bin, I think you have 100% authentic AR-3 loudspeakers, no question there. What I do see, however, is that someone has tampered with the labels on the back and altered the serial numbers. I know that those serial numbers are not authentic, mainly because of the supporting evidence we've reported. You've raised yet another question, why weren't these speakers signed-off? I've never seen a pair that got through final inspection without a signature; it was required of the quality-control employees to sign-off on everything that went through the plant, from the anechoic testing of each individ
  15. Why does it even matter?
