Nagra IV-SJ Reel to Reel with Accessories and 10″ Adapters Nagra IV-SJ Reel to Reel with Accessories and 10″ Adapters General: If you’ve not had a Nagra piece of equipment you’re for a treat. It’s by far my most favorite manufacturer, as their products are built like Swiss watches and utilize a level of precision and engineering found in only a handful of European brands. Never mind that they look so cool! Nagra IV-SJ is the Enhanced version of IV-S that came out in 1972. This was an instrumentation recorder for precise noise and vibration measurement and other scientific audio analysis organisations. Equipped with special microphone preamplifiers, modulometer, and stepped input attenuators, the IV-SJ is uséd for a multitude of different environmental and industrialization applications. Customers for the IV-SJ varied from NASA to Rolls Royce and Greenpeace, and it was commonly uséd to record whales and ultrasonic waves. The IV-SJ also makes for a formidable audio machine with a super low noise floor and great dynamic range. Check out our SkyFi YouTube channel for a video I did a while back on a different machine of the same model. This machine had an easy life and was well cared for as indicated by its cosmetic condition. It looks super and presents very clean. To get this machine to the highest level I performed several upgrades: • Custom high-quality output cables with RCA and DIN. • Custom high-quality switching power supply. • Large 10.5″ reel adapters made of machined aluminum which bolts to the back of the unit. • 10″ Aluminum take up reels (2). In addition you’ll get the original acrylic hinged cover that’s usable with the small reels. Brand Background: Nagra is a brand of portable audio recorders produced from 1951 in Switzerland. Beginning in 1997 a range of high-end equipment aimed at the audiophile community was introduced, and Nagra expanded the company’s product lines into new markets. Originally a product of the Kudelski Group, Nagra recorders are now developed, produced and sold by independently-owned company Audio Technology Switzerland S.A., based in Romanel-sur-Lausanne. The machines were initially designed by Polish inventor Stefan Kudelski,[1] and his company won numerous technical awards for their precision and reliability.[2] Nagra means “[it] will record” in Polish, Kudelski’s mother language. Nagra-brand tape recorders were the de facto standard sound recording systems for motion picture and (non-video) single-camera television production from the 1960s[3] until the 1990s.[1][4]” Ownership: Second Owner Connections: European DIN with included cables (See Photos for exact cables included) General Sound: Accurate to the recording Cosmetic Condition: 7 – Some Wear and Light Scratches Working Condition: Working perfectly and tested in our lab.

Testing Process: The SkyFi Testing Process for Tape Decks and Reel to Reel Machines: First steps are performed to determine if the unit is a candidate for our full restoration process or if its just in need of a light service. We first do a basic functionality test to ensure proper playback fast forward and rewind. We look for smooth operation of the motors, transport engagement and associated rolling parts. We then do an internal physical inspection to ensure the belts and rubber consumable parts are up to spec. Internal components are checked to make sure that there are no signs of heat stress or damage particularly in the power supply section. Capacitors are checked for telltale signs of predictive failure including bulging, shrunken wrappers, or physical leakage. We also inspect the PCBs for discoloration from resistors or transistors that may have been running hot. On vintage units we often spot check select capacitors for value and ESR. A light service will involve replacement of belts and rollers, external cleaning of heads, mechanism and boards and basic record and playback tests. A full restoration will often include disassembly of the drive system and replacement of all consumable and wearable parts including pinch rollers, belts, brakes, bearings. We then clean lubricate and re-assembly the drive and perform basic mechanical alignment to ensure proper tape path and head alignment. Final calibration will involved adjustment of playback erase and record heads and optimization of the bias for a specific tape type. We do this with the aid of a Soundtech 1510A tape deck analyzer and a Nakamichi T100 unit and reference calibration tapes. Final listening tests are done while monitoring with our reference Grado HP1 headphones and a variety of factory and custom reference recordings. We find that there is no better system for critical listening on tapes than the headphones specially when comparing a live feed to a recorded feed.
