  1. C. Victor Campos C. Victor Campos, 84, from Framingham, Massachusetts, an alumnus of Acoustic Research from 1960 until 1963 and again from 1974 until 1979, died on December 11, 2017 after an extended illness. Victor briefly worked at AR's Music Room in New York in 1959 and later worked in customer services and assisted Ed Villchur with the production of the Live-vs.-Recorded series in the early 1960s. In 1963, Victor went to competitor KLH Research and Development Corporation to work in customer service and engineering under Henry Kloss, but he returned to AR in 1974 working with the Advanced Development Division's new speakers. During these years, Victor produced a superb series of FM broadcasts out of Boston, "Adventures in Sound" and "Shop Talk." These broadcasts were done with master tapes without compression, usually challenging a FM listener's high-fidelity equipment; i.e., if you did not possess AR heavyweight loudspeakers in your system, you were likely to sense distortion during playback! These were superb reel-to-reel tapes done on Ampex AG-440 machines and similar high-end transcription recorders. In the mid 1970s, Victor produced the excellent Neil Grover (drums)/AR-10π live-vs.-recorded demonstrations that showed the extremely capable and accurate reproduction of the AR-10π, especially reproducing the bass drum at high levels. This was a very difficult demonstration—in ways more difficult than the Fine Arts or Gustavo Lopez demonstrations—requiring enormous amplifier peak levels of over 800 watts per channel to reproduce the peak acoustic levels. Steve F on this site attended at least one of those demonstrations and can elaborate on the effectiveness of that demonstration. Much of the credit for the success was due to Victor Campos' understanding of amplifiers, loudspeakers and tape recorders, and he was able to produce excellent results during these LvR demonstrations. Before Victor left AR (he was also at Adcom and NAD through the years), he was very instrumental in the development of the AR9 tower loudspeaker. Initially, Victor wanted the AR9 to be a "powered" speaker complete with built-in amplifiers for woofers, midrange and tweeters, but he was not successful in that quest! At times, Victor could go overboard: when the AR-10 was being developed, a problem occurred with hinge on the fold-out solid-walnut access door on the front. It would bind and stick. Victor wanted to quit "experimenting" and simply cut to the chase: add ball bearings to the hinge! Of course, this was much too expensive, and a proper hinge was developed which worked well without problems. His influence was felt! Victor was an intelligent but sometimes impatient person, yet he accomplished a great deal in the years he was at Acoustic Research and KLH. He will be greatly missed! —Tom Tyson 12Dec2017
  2. I have a KLH Twenty One FM radio that we bought new in the 1970s. My wife would like me to get it working again. The problem seems to be that the speaker distorts ("flapping sound") at high volume/bass content -- Ok for voice range but music creates the problem. No obvious tears in the surround. Your advice on what avenue to go down next to restore quality sound is much appreciated. Has anyone found an off the shelf speaker part that is a good replacement should it come to that? Are there other things I should do first? Thanks in advance.
  3. New to this forum, and to warn you been kicked out of better places? OLD Submarine Sonar Tech, Electronic Tech. Retired, back into sound. Kinda JBL guy, but many Vintage brands have come and gone. JBL are easy to turn with good margins?. But as things go. KLH17's $20 rich house next to BMW in garage. Passed husbands. After a little chat and smiles, I filled her in on her husband good choice, and she was so touch, she gave them to me. Accepted with big smile and booked. KLH 32's NIB Yes NEW IN BOX !! CL for $120, waited patiently for 7 days, BO for $40? NEW IN BOX. Both will need "Old Age" issues addressed. That is how I got here to learn about cloth surrounds. So any thoughts, impressions, MODs? Thanks All
  4. I recently acquired a pair of KLH model 28's. I know they are rare, but are they collectible? They are too much speaker for me, so I'll probably be selling them. Man can they part your hair. I'm just trying to figure out what I got. Thank you for any help. DJ BTW I have AR-5, AR-2ax, AR-4ax, and KLH 17's. I like them all.
  5. Hey Folks, One of my KLH Seventeens started going intermittent on me and tapping on the woofer made it come back. I looked at the lead wires and it looks like one of them isn't making contact well. Looks like the lead wires are just crimped and not soldered or glued. Are all KLH leads always just crimped? I'm hesitant to take an iron to the cone, but will if I have to! Suggestions from those with KLH experience? First pic is the offending speaker, second pic is the one working fine... (did my best to get the camera to focus): https://i.imgur.com/P0CN7k5.jpg https://i.imgur.com/p9hJPR0.jpg Thanks!

    KLH Model 12s in RI

  7. Report post Posted 5 minutes ago Hi All, I'm brand new to this forum and I like look/sound/vibe of vintage stereos but I know nothing, nada, zilch about them. I recently bought a KLH turntable that is in excellent condition, but they came without their speakers. On another shopping trip I found a gorgeous pair of vintage Wharfedale W 60 c speakers. So I have a few questions (go easy on me I am 100% a novice here)" 1. Can I use these two together? 2.If so, lets move onto the next question: I tried RCA style connections in the back of the turntable and they seem to fit. So I'm assuming that I'll need an RCA connection on one end, and then strip the wire at the other end of the connection to attach it to the Wharfedales? 3. It appears as if there's only room for one set of RCA connections. Does it matter if the Red goes in the left or the right? 4. I *think* this is the wire I need? Right? https://www.amazon.com/AmazonBasics-2-Male-RCA-Audio-Cable/dp/B01D5H8P0G/ref=sr_1_3_acs_sk_pb_1_sl_1?s=electronics&ie=UTF8&qid=1543365982&sr=1-3-acs&keywords=rca+cable 5. Since there is only room for 1 of these sets on the back of the turntable, do I split the unit into two distinct wires (the red side and the white side), then strip the ends of each of the two to reveal the underlying wire. and then split the bundles of wires to wrap around the red/black posts on back of each of the speakers? Any help you all could provide would be very much appreciated. I really didn't realize as I started finding these components that I'd be so incredibly confused. Thanks in advance! Erika
