  1. I was looking for something Phillip posted earlier about DAT recorders and blenders and I came across this new Member. I can't believe I miss this valuable new member to JWsounds Nagra Thread. It's always a good thing to have another Nagra tech for advice and help. Mike asked if anybody had a Circuit diagram for a BM mixer? A few commented and gave advice, then new member Nagra Tech chimed in and BAM!! Produced the diagram. Very nice! I guess Nobody even noticed who posted. Thank you very much Nagra Tech from Nashville Tennesee. Thank you for being so helpful and posting the Circuit Diagram. That was very fast service that went unnoticed for a long time. You're noticed now! Steve George Remote Audio, Nagra's newest North America Distributor
  2. What I get out of this video when I watch it. I think back when I was in school there was always a teacher just like him, I’ll bet you can even name one or two. I can, Dutton and Lewinski come to mind. The Senator is very into what he’s talking about. He doesn't just talk, he explains, and in his way of explaining he always sets up the scene in a series of little bits of information in a way that is very easy to understand the outcome. He just doesn't come out and say the answer and move on. There is no, what do you mean? or I don't understand after he says something. I don't know how long he taught but anyone can see he is very good at it and is a no-nonsense type of teacher. I can picture he acts the same way in the classroom as on the forum when someone asks a question. I can see him firing away at that student with a number of questions. I can also see how he brought this way of teaching to the forum, not on purpose it's just the way he communicates as a teacher. You ask anywhere near a stupid question in Dutton's class he would work on you till you said the correct answer to the question you asked. I think it would be a much different encounter in person one on one or in a classroom with the Senator. With him helping someone to understand and I'll bet he would ask you a series of questions (set up the scene) needed for you to come up with the answer on your own. Just like any good teacher would, they just don't give you the answer. They make you stop and think and work for it. On the forum. Answering In a series of 2 sentence posts may come off snappy and not like he's trying to help you but he may believe he really is. He just won't say the answer right off the bat just like he did in this video he sets up (the scene) before giving any answers, that is the way he does it. He did that in everything he said in the video on every subject he talked about. On the forum, there is no time to run the series of questions post by post as if you asked in real time (if that makes any sense ) In a post, its a lot harder to do for someone who asks a question and has no patience for the answer. Completely understandable on both ends, but that may be just the way it is...
  3. Thank you for posting that Tunes, I would never have seen it. I looked, couldn't find anything about it. Don’t beat yourself up over it unless you were willing to pay more than a grand. Even if he left the auction up you know that guy was going to bid a grand or more. If anything I can see you being mad at me for advertising it. I didn't think anybody on Jwsound was interested in this covert part of my collection. I really do think if the seller left the auction alone he could have doubled that price. I don't believe he used it three times in the field either. Its new old stock. Once the PS-1 was out they were useless. I could be wrong. I'm surprised someone who used it would not fold in or fold out the JBR base in any of the seven pictures he took. But with the title of his auction NAGRA JBR tape recorder adapter SN I knew it would be hopeless to get this at a good price, so since I already have one I shared it on Jwsound. I did want to see what it would bring and it gave me a chance to post the JBR story again. There are details in my JBR story that were never made public "anywhere" only here on Jwsound. So every now and then I bring it out of the place it hides.
  4. https://www.ebay.com/itm/NAGRA-JBR-tape-recorder-adapter-SN/401741109290?hash=item5d89a2d82a:g:vRgAAOSwsYtcojS4 Oops! The old error in the listing take down line. Thats too bad, I would have liked to see what it would go for. I guess that backfired on me. Sorry if anyone saw that auction and bid on it before I posted about it. On Apr-05-19 at 11:19:00 PDT, seller added the following information: GLOBAL SHIPPING is via ebay global shipping This listing was ended by the seller because there was an error in the listing. Either he is going to realist it or someone got to him.
  5. A very rare piece of Nagra and FBI history is up for sale on eBay. You may come across a JBR someday but you may never find the Nagra CST adaptor. I do not know this seller. What Ido know is what I wrote below. This adaptor is what the FBI had to use (for two years) to play back a JBR cassette. Seller states "Nagra SN permitting playback in "the field" without the large JBR playback unit" That was not what this adaptor was built for. This adaptor could not reproduce any of the features the Nagra PS-1 could. It was only a stop gap to get by until the advanced PS-1 was finally developed. https://www.ebay.com/itm/NAGRA-JBR-tape-recorder-adapter-SN/401741109290?hash=item5d89a2d82a:g:vRgAAOSwsYtcojS4 The Nagra JBR, 1984 written by RJW The Nagra JBR (Junior Body Recorder) was perhaps the most needed covert recorder advancement of the time when it was introduced secretly to the FBI in 1984. It was a joint venture between Nagra and the FBI and 2 other three-letter agencies of the U.S. The aging SNST was still in use at the time and still very popular, but everyone "in the know” knew how to detect someone using the SNST. The SNST was large and cumbersome for one to wear secretly on their person. Not to mention the person on the other end of the conversation most likely was using an advanced tape recorder detector of that time. A smaller-sized harder to detect recorder was needed so Nagra, with the help of (James B. Reames* of the FBI ) developed this smaller, harder to detect covert recorder, possibly the most secret recorder ever contracted. *James B. Reames 1958-1990 Federal Bureau of Investigation Washington, D.C. Responsible for the analyses of audio tapes to improve intelligibility, to identify non-voice signals, and to determine authenticity of magnetic tape recordings submitted by Federal, State, and local law enforcement agencies. Also involved with the FBI’s Tape Enhancement Laboratory, Tape recording Capability, Research and Development Activities, Technical Security Counter measures programs and Tempest Programs. The project was kept highly secret, even to the people who would eventually be the ones using the new JBR, for reasons to also weed out any bad characters even within the government agencies themselves. The recorder could now be used to expose people that knew how to detect the SNST and other recorders of the time. They certainly would not be suspecting the new hard to detect JBR. “The design and manufacture of the recorder has been so secret and important to the FBI (and two other unnamed government agencies who are supposedly the sole users of the recorder) that any public availability of information on the recorder would ‘’make the machine extinct,'according to an employee of Nagra who refused to provide any details on the recorder in a telephone interview." (1) The complete project was spelled out from the beginning, the JBR recorder along with the advanced universal playback unit called the PU-1. The proposed PU-1 was designated to be a “Playback Universal Unit” to be able to play back the SNST reel tapes and a JBR cassette (a multipurpose unit). The JBR and Playback unit was very advanced technology at the time that was never realized before in a recorder of this size. Since the JBR recorder was easier to develop, the JBR and the playback unit were not ready at the same time. Due to time restraints, the JBR was delivered to the FBI without any means to play back the recording. As the JBR recorder started to be used in the field, the playback unit was still in development. There were many delays as this “new” technology was being developed. The center control track on the JBR was to speed correct the tape since it didn’t have a pinch wheel. The speed of the tape and motion while worn were not going to be an issue because of the control track. Everything was thoroughly thought out in advance, except for the delays. The customer now had “ evidence tapes” and no way to reproduce them, due to the lack of any available playback device. A mechanical adapter was developed: Called the CST to work in conjunction with a common SNST to playback the recorded JBR cassette. This adaptor was one thing that was not in the original plans. But it was a way to play back the recorded JBR tapes while the advanced playback unit was being developed. This was not a cheaply put together adaptor it was made in the same fine quality like any other Nagra product. Its almost as Nagra knew it was going to be awhile before the “PU1” would be ready. A couple of issues emerged: The tapes did not have any speed correction since the SNST host machine didn't have the capabilities to read the control track. Because of the speed issues and Wow & Flutter, the customers started questioning the quality of JBR recordings. Of course, it wasn't fair since the whole concept hadn't been realized yet. No PU-1 or PS-1. A control track filter SCTF, was developed to remove the control track tone from the audio during playback. No one wanted to hear the high-frequency tone mixed in with the audio evidence. If not for that filter, the SNST would otherwise reproduce the constant control track tone. All of these things were stop-gap measures to calm the customer. (FBI) The other main flaw in the mechanical adapter was its hold-back tension. It was so high; it damaged the tapes when used. With a few gear changes, they got it to work, sort of. (2) The CST adaptor was made utilizing a Nagra SN housing: The SNST would slide on top of the SN housing and lock securely in place, and the folding arm would swing out and hold the JBR cassette also locked securely. Underneath the cassette was a fold-out rewind crank like on the Nagra SN for manually rewinding the JBR cassette. It was very well built. Nothing speaks vintage Miniature Covert Recorder like this set up in playing back the recorded evidence tape. It just goes to show in this clandestine world, you gotta do what you gotta do. The folded CST unit Bottom side with the manual SN rewind crank, this is also used to remove any slack in the tape. The JBR cassette mounting plate swings open and locks, the SNST slides and locks into place. Add the DSP playback amp and this was the first playback setup before the Control track Filter was developed, you can see it was a continuous work in progress to satisfy a growing impatience customer. In year two, I was going to post a scan of the instructions for the control track filter, but because of a schematic on the back side stamped “do not reproduce” I am not going to post any part of the original document at all. The drawing is dated Oct 1985 The Control track Filter is just a small box that fits between the SNST and the DSP playback amp. and the ASN power pack. So the CST adaptor was used without the Control Track Filter for almost a year before the filter was developed. The “make-do” playback required these five items from the original Nagra document ASN Power pack, SNST recorder, DSP playback amp, CST mechanical adapter and the SCTF control Track Filter. (3) Together they completed the setup required to play back JBR tapes in its early years. This was the only means available to play back a recorded JBR tape for two years. The PU-1 dual use playback unit that plans called for an SNST and JBR combination unit was scrapped and never realized. In 1986, the PS-1 playback unit as we know today was finally delivered to the FBI For the first time since the 1984 delivery of the Junior Body Recorder the full potential of the JBR system was finally realized. The harder to detect recorder was only one part, but the advancements made in the PS-1’s capability in enhancing the playback sound was just amazing. Either Nagra or the FBI dropped the planned universal dual playback (PU-1) for whatever unknown reason. The JBR - measuring only 4½” by 2½ - with the PS-1 playback system was the smallest most advanced analog recorder system ever produced. One of the hardest stumbling blocks of using past covert analog recorders, including the SNST, was the ability to capture clear quality evidence recordings consistently. This was now made easier thanks to the adjustable JBR playback system of the mid-eighties. It was all so secret and no one could speak about this advancement in reproducing analog recordings. Of course, digital soon took over, and another Covert Recorder quietly and without fanfare goes down in history. Below An original Nagra JBR advertising poster showing a JBR beauty shot, with the cassette cover removed to show off Nagra’s reel to reel covert recorder roots. This extremely rare poster from 1990 was meant to be used for advertising the JBR at Intelligence trade shows, but its use was short lived as Nagra was informed not to advertise the JBR. The reason was stated to me below. As I advised, xxxxx xxxxxx told me that Nagra New York received a letter from the FBI advising that these recorders were an Interception of Communication (IOC) device and if Nagra continued to advertise these units, there could be legal percussions. I don’t think Nagra advertised the recorders in the USA again. (4) "The Nagra JBR along with the SNST miniature recorders were categorized by the U.S. Department of Justice to be Interception of Communication Devices (IOC).” “The IOC statutes make it illegal to own, use, train and/ or educate non-law enforcement personnel to use this equipment.” (4) Sources for the Nagra JBR 1) From - Full Disclosure Newspaper, Libertyville, Illinois (USA). 1991 2) Anonymous former Nagra employee 3) SCTF instruction manual. 4) Anonymous intelligence source.
  6. Post 466 of Nagra Stories provided by Dejan Ceko from Serbia is very interesting how movie sound is created or enhanced after a movie is recorded and really explains a lot. I never knew that. Shown here in my quick index on page one #466
  7. The Nagra LB, The prelude to the Nagra 7 the LB is one of my favorite Nagras. It’s small, compact, loaded with all kinds of options (some obsolete). Nice looking with all manual controls, dual screen, led level lights, built-in microphone, speaker etc. It was too close to the improved Nagra 7 with all the controls on the touch screen for about the same price of the LB $3500.00. It was assembled in China to keep the price down. That’s ok, it’s still a Nagra, doesn’t mean it's cheap being assembled in China. Just think how much it would have been if Nagra put it together. With the Nagra Seven there was no longer the need for the Nagra LB, especially with the same price tag. Oh yeah and the case is all machined aluminum, no plastic. I was lucky enough to get this one for 1100.00 a couple of years ago. I was told it was bought for a project but the project was canceled and they no longer needed the recorder. The recorder does not look used at all. I wonder if there is a time used menu on it? I had to yell to get the led level lights to come on for the picture. "the Nagra LB, one of the coolest looking Nagra recorders. Small, compact, hints of old and new, nice and busy loaded with controls and options"
  8. More Nagra Art Last week I picked up a NOS Nagra III deck plate, very reasonable. I thought why not, that would make a great addition to my collection. A Kudelski picture to hang on the wall. Nothing says, “KUDELSKI” like the Iconic Nagra III reel deck, deeply acid etched by Stefan Kudelski. Designed in 1957 the Nagra III was a major change in the way movies were recorded. Stefan Kudelski lives on in so many ways. Both the deck plate and the reflection reflect the accurate color and depth of the etched artwork on the Nagra III deck plate. Zoom in for details.
  9. Scott, Nagra made anodized Blue Nagra E's only for Radio France. Red for everyone else as far as I can tell. Took me by surprise when I first saw the Blue Nagra E, thinking someone must have re-anodized the deck in blue but Radio France is machined stamped into the upper left deck corner as shown. I bought this from a seller in France.
  10. Ahh, very nice what your friend did, Blue and Red Nagras. Now, what does that remind me of … oh yeah this picture. Time for a glass of wine, or Shaken, not stirred. Two? Of course, Bond always had a woman, he just never had a NAGRA 😎
  11. Thank you Raquirk, I appreciate your comments and your interest. Can I ask how did you find this thread on Jwsound? That was not a Nagra SN in the opening credits of Klute shown below. It was the fourth recorder in a series of covert recorders made since 1957 Its was the first in this series to have a name on the recorder. Below is a short writeup that I have done. Type 4, EDI Recorder, Circa 1967-68 by RJW Size including controls w h L 2 3/4 x 1 x 5 1/8 inches Weight 10 1/8 oz. Diameter reels 2 3/16 Tape 1/4 inch Other technical features detachable remote control Two different models EDI M60 mono version and M-75B as a stereo version. The Type 4 recorder in this series of CIA recorders is very similar in construction to the Type 3 recorder. The cover is a non-painted, anodized aluminum lid and a greenish-gray wrinkle-type finish base and, for the first time, there is a name on it. Called simply, edi. It was manufactured in 1967 by ElectroData Inc. in Fort Lee, New Jersey, thus the initials edi. Earlier models of this type made by the same company were kept secret as to who made them. As this July 1967 Electronics Illustrated article shows, these were now known to the general public. It shows a picture of the past secret model. (7) see figure xx The company did not provide a prototype or even a picture of the new 1967 model to show for the magazine as the article states. There were two new models for 1967; there were the EDI M60 "mono" version and a mistakenly called B60 stereo version. The correct model number is M-75B for the stereo version. That is this type 4 recorder. It is not known if the CIA continued to use this model. Now a name appears on the recorder for the first time, and the recorder is now made public. This may confirm that on this date, July 1967, they were no longer used by the CIA since it shows the secret model and the new models are now being sold to the general public. The manufacturer is now allowed to produce and sell these recorders publicly. Now the manufacturer has to name the new recorder if they want to sell to many different consumers, so names on these early recorders may have been a sign of who and who was not using them. There were other improvements on this public model. Not only was it dressed up cosmetically with a two-tone finish, but it also added features over the previous model like an auto stop. That isolated silver pin on the right front of the deck was used in conjunction with the ground circuit as an auto stop. A piece of 1/4 inch metal tape would create the circuit using that isolated pin and ground from the head, causing the tape to stop. see figure xx In 1967, cassette tapes were starting to become more accepted, but nothing yet available in this size range. This auto stop was an added convenience for the user. It meant you would not have to re-thread the tape on the reel when turning the reels over to record on the other side. (B/W wiring diagram pic *4) Also for the first time, a removable remote on/off switch that is attached to the microphone/ headphone plug. It's clear these models were evolving by what was tried and tested through the years. This Type 4 recorder was featured in the 1971 movie Klute with Jane Fonda and Donald Sutherland.
  12. No excursion, Stefan Kudelski is Nagra… thanks for posting the story. NAGRA the legend lives on…
  13. Two words in his own words -- Video starts at exactly 34:29
  14. Since nothing else worked, Its clear everyone now is reduced to goading the Senator to make his Iconic answer “It depends” that's because people now realize the answer always made sense. I'll bet two words will get 3 pages of welcome back.👍
  15. I call this The Best of Nagra Photo from Nagra Audio Facebook Stefan Kudelski really had a way working with aluminum like no other manufacturer. All products look fantastic shown like this. To think I sold my Nagrafax, sold my IVJ, never could afford a Nagra T. All sold to buy the rarer SN's JBR Nagra II etc. figuring someday I'll buy them back because they were more common. Now, with Nagra prices going up weekly I may have made a big mistake thinking I could always get them back. The 4s is very popular with Nagra High-End audio equipment, isn’t it amazing, what a run that machine has. I predict there will be a big market for what's left of the used Nagra IVS’s in the future. Supply and demand. So many pictures and videos on Nagra Audio's Facebook page shows the Nagra 4S top front and center. Think about it how could you ever own this ultra high-end Nagra Audio system without a 4S That is why people are paying 5 6 7,000 for them. I think that's great news for Soundmen, you will be making out pretty well with your vintage Nagra 4s if you wanted to. There is also a company that is remaking the large reel adaptors for about a grand. Does anybody have one or know someone that owns one of these high-end Nagra Audio Systems? They have been winning all sorts of awards. What a legacy Stefan Kudelski has left behind.

  16. Here you go Jon, I also send you a picture of a cassette recorder prototype that I found at my father home. Have a nice day Best regards Marguerite Kudelski
  17. Im very sorry Michel I miss your 1st post and did not comment. I just came across your post today by accident. Thank you very much for posting. There are very few Public Nagra collectors. As far as I know this site Jwsound is the only place where Nagra's are talked about between collectors and others in the US and the world as far as I know, do you know of any in France ? I would love to talk you and see your collection and share information with you. Best way is copy and paste my text or any text on this forum into Google translator. https://translate.google.com If its easer for you just post in your own language and I'll do the same if that is ok with Jeff? Je suis vraiment désolé Michel, ton premier post me manque et je n'ai pas commenté. Je viens de tomber sur votre message aujourd'hui par accident. Merci beaucoup d'avoir posté. Il y a très peu de collectionneurs publics de Nagra. Pour autant que je sache, Jwsound est le seul endroit où l'on parle de Nagra entre des collectionneurs et d'autres aux États-Unis et dans le monde, autant que je sache, en connaissez-vous en France? J'aimerais beaucoup vous parler et voir votre collection et partager des informations avec vous. Le meilleur moyen est de copier et coller mon texte ou n'importe quel texte de ce forum dans Google Translator. https://translate.google.com Si c'est plus facile pour vous, postez simplement dans votre propre langue et je ferai de même si tout va bien avec Jeff?
  18. PiO, I think you should have added "to me" at the end of your statement above. I did not realize you were not a collector. My post saying it does have historic value meant it is my opinion that it does. It's not or never will be in the IV-S league or price range. I'm sorry if I gave you that impression. Maybe your right, to most people it will not be viewed historically. You are always welcome to donate it to the RJW Collection where it will have historic value in the context of the collection. Thank you very much for sharing your Nagra III with Jwsound. I appreciate you posting this information very much.
  19. At a minimum its worth 500.00 on eBay right now as is, without even explaining the year.
  20. Are you kidding no historic value ? Not sure why you say it has no historic value, you have the earliest known Nagra III. yeah, it shows some history its 61 years old. It has some battle scars and some up grades. So what, it's still what it is the earliest known Nagra III to date. As long as it has that serial number it's worth much more than you think. You can spend the next 10 years or the rest of your life for that matter and never see another 1958 Nagra III that you can own. Once you change the belts you may see a big difference. I saw a third jack somewhere and it was marked ground, not sure why it had two grounds if I find it again I will post a picture. I think Glen Trew could answer any question you could ever have about a Nagra III mechanical issue. Where did you get it? Try and find out its history. At this point I would say a sound man in France owed the machine. A news reporter did not upgrade to a pilot model.
  21. I thought long and hard to try and figure what "a. o. used" meant, finally I said screw it, I looked stupid before, I’ll ask. Never would have figured “amongst others” Maybe I should try and add some random letters and periods to see if people are paying attention to what I write. Cause coming right out with it clearly, like, anyone want to see a Gold SN or the SN prototype doesn’t work very well for me.😊
  22. Thanks, Dela for that information. I didn’t know they came with the test tapes, that may be why we don’t see too many of them. I have only seen red and green anodized labeled test / adjustment sets in the past. Always wanted to have a set but they were always selling for a lot of money. The gold ones I have are just tape, I think, they came from Italy maybe they are unlabeled test/adjustment tapes, never tried them. That would be something If I had them all along. I know they are full of tape, I didn't think adjustment tapes had that much tape on them? Can you just clarify what a.o. means.
  23. Lermontov, Nice pictures, I went back and looked at your other posts, you are a passionate Nagra collector as I and as many others are. Since you are the only one in almost 3 years that asked to see the one of a kind Gold anodized Sn that was built especially for Mr. Kudelski as a surprise. I thought I would share this Nagra moment in history with you and others, I don't think MK will mind. This story goes to show that Nagra employees were thinking of adding color to their famous Nagra SN recorder. They produced "one" SN in a gold color as a test to surprise Mr. Kudelski. As the email reads he did not like it at all thus the reason why the color of the SN remained silver. The picture at first glance just looks like a normal SN but then you see the contrast with the non-gold anodized parts, it is a very special picture of a very rare SN along with the short story. I imagine they used many already made silver parts in this test. They did produce the anodized Gold SN reels I own a few, I may have five of them. I'm not sure if they had the Gold reels already or they made just a few when they made this recorder but Gold metal SN reels do exist and they are very rare. You hardly ever see the gold reels in pictures. The gold recorder from what I understand is only the one shown. You can see the reverse contrast of my gold reels against the common silver SN in my picture below. Now, will see how long it takes for anyone wanting to see Mr. Kudelski's prototype cassette recorder that no one ever knew about. Mr. Kudelski loved his life's work and loved experimenting on his own in his factory even though he no longer needed to, as I have been told from my Nagra source Dear Mr. XXXXX Thanks for the interest that you have to our device. As XXXXXXX answered, this prototype is not to sale because it is part of the family history. I’also remembered of your pictures. As you are a Nagra lovers, I send you a picture of the "Gold color" SN test. For the short story, this test was conducted in secret without notifying my father and let him see the surprise…As the result, my father wasn’t not at all pleased with this proposal, so this is a reason why the SN is only in grey color! Have a nice day Best regards Marguerite Kudelski
  24. Your neighbor calls asking if you can help get her tractor running, You rush right over and this is what You find. Would you wake her and help start her tractor? Stand there and wait till she wakes up? Or Go back home and read JBond’s Nagra Stories Again, using the quick index? So many questions.
