  1. Aloha, having lived in Denver for a number of years, my choice for serious matrix recording has been the Sennheiser MKH 30 and MKH 40 mics. I send the signals into my Audio Developments Preamplifier/Matrix AD066-11 system. I can record into the box with the ability to adjust the stereo spread by increasing or decreasing the channels. Another feature using this AD066-11 is the ability to individually adjust the gain on each channel. When I arrive at the final sonic configuration I simply feed the signals to my Nagra 4STC stereo recorder. The Sennheiser mics have a very high sensitivity perfect for Nature recording. The AD066-11 also functions as  post production. A return signal can have it's width controlled. All of this gear is easily used in the field for great recordings. Hope this helps. Thanks

  2. Aloha, the Film Group actually made a resolver for your Sony TC-D5M and they called it Sony TC-D5M/Pro11. They modified a standard TC-D5m recorder to accept and include a sync resolver system. You may want to go on line and look up The Film Group. They have published all there products including the resolver. Cheers 

  3. Aloha, I have the Nagra 4S service manual. It is not for sale or loan. However I would be willing to copy a few of the pages to help you with your project.  The manual starts with the mechanical section and then the electrical section. Any adjustments or calibrations appear in these sections. I have no idea how they could be sent to you. I wander if USPS goes to Brazil. Anyway please advise if this will help you.

  4. They are extremely rare, why not just send your Nagra to Steve George.

    Location Sound may be able to help. Ask for Mike Paul. 1-800-228-4429. Last time I saw him he had all the manual. You may only need part of the Nagra Service Manual. Reproducing some of the schematics may help. Another possibility would be Trew Audio. Cheers

  5. Aloha, I have gone thru about half of my Nagra111 info. I have found a number of original schematics for the modules in the Nagra. These detail resistor and capacitor specs by size and part number. I have also found the original Nagra principal schematic. For example the preamp-micro shows the schematics and details by "R" and "C" numbers and size and value. I also have a number of Nagra111 operation manuals, the most significant was1963. Perhaps an effort by Nagra to really show the importance of their products. They used very impressive pictures of Nagra in use. The brochure is loaded with their specs. Hope this may help somebody in effort to better understand the Nagra111. Enjoy your day

  6. Aloha, looks like the pinch roller needs replacing. The replacement roller would be the standard Nagra 4 series roller, and with the bearing and shaft, and all spacers. The main holder of the pinch roller can be lifted up by removing the large center screw, and loosening the side Allen screw. The main shaft is held in place with the "C" snap ring which has been known to take off if not carefully removed. Just replace all the existing bearing parts, clean the existing support and install the new pinch roller, lightly lubricating the parts. Re-assemble the main support adjusting it to the proper tension for your tape. Should work for you. A note of importance, the new pinch roller should be yellow in color, as these rollers wear, they turn towards red in color, finally the black rollers are inclined to be worn. The color change is influenced by tape and oil contamination. Cleaning the new roller after every use will help to retain its new appearance. Regarding a Nagra 111 manual, I have a lot of Nagra literature and manuals and I will research thru all that I have. Nagra never really had a service manual. I would expect Nagra began to direct their attention toward the Nagra 1V  which surfaced in 1969/1970. Enjoy your Nagra 111, still today they are great machines     

  7. Aloha, living in Hawaii I have had extensive experience with the Aquaear MKII hydrophone. It is a great mic, performs very well underwater. You can find out more about this product by going to www.burnselectronics.com.au/prod)01. They also make all the power supplies well as the hydrophone preamplifier/ amplifier. Check it out, it very well may be what you need. Thanks
