Grado 78C Cartridge

Optimized Transmission Line (OTL) Cantilever/Stylus Assembly Grado's OTL provides an ideal transfer of the signal from point to point, e.g., stylus to cantilever to magnet to coils, etc. This has been achieved by eliminating resonance at each of these key junctions. The transmission line cantilever consists of separate sections that are telescoped into each other. All sections are made of different alloys, some sections hollow, other sections solid. These sections are bonded together with materials that act as dampers, and are coated with a black proprietary material which controls and absorbs resonances that travel on the surface of the cantilever (known as skin effects). The OTL stylus/cantilever design will make your records sound quieter, improve the height, width, and depth of the soundstage, and offer more detail than previously obtainable. Cartridge Holography does exist...and that is what Grado's OTL technology is all about, more performance. Pivoted-Fixed Axial Cantilever/Stylus Generator This design feature is basically quite simple. The "OTL" cantilever shaft is brought to a fixed axial pivot that supports the entire cantilever assembly. A miniature element attached to the end of the cantilever is allowed to move freely within the lines of flux of a stationary magnet and coil structure. This system of support is mechanically more accurate (more linear) than conventional "teeter-totter" designs that utilize an iron armature to balance the mass of the cantilever. The teeter-totter design is supported in the center with a rubber donut mounting. The fixed axial design has a very low tip mass, which results in lower distortion, improved transient response, and longer record life. Flux-Bridger Generator System The Flux-Bridger design uses four separate magnetic gaps that the miniature element of the cantilever bridges. The miniature element moves between opposing flux gaps creating an increase in flux in one gap while reducing it in the other. The four separate magnetic gaps create a highly efficient and perfectly balanced system. This design requires fewer coil turns than conventional designs. The Anatomy of a Grado Phono CartridgeHand-Built in the USA With 100% Quality Control Each individual cartridge manufactured by Grado is hand assembled and tested for frequency response, channel output, channel balance, phase linearity, inductance and resistance. This meticulous care in design and construction lavished on each Grado cartridge contributes to an unchallenged consistency of performance and guarantee of reliability. Grado's Prestige Series of Phono Cartridges The Prestige series of cartridges are designed for high output and excellent stability under severe use. A considerable tip mass reduction results in a frequency response to 50 kHz and beyond and tracking forces from 1-2 grams. Acclaimed by experts as virtually the finest pickups in the world at their price. Prestige models available in both 1/2" mount and P-mount. All styli in the Prestige series are user replaceable. Grado 78C Details The Prestige Series of 78-RPM cartridges are designed for high output and excellent stability under even severe use. Each cartridge can be used for either archival or casual play without concern for undue wear on the record. All Grado 78 cartridges have a considerable reduction in tip mass resulting in extended frequency response while tracking forces can range from 2-5 grams. The experts acclaim these cartridges as virtually the finest 78-rpm cartridges in the world. The Prestige model 78C uses a three-piece OTL cantilever technology, oxygen free wire in the coils and a specially designed, high polished conical/spherical 3 mil. diamond mounted in a brass bushing.

    Altho' it sounds great on my Technics 1200, it's just a slight bit jittery on that tonearm, even at the max. tracking weight. I'll usually set the arm on by hand, and not by the cue lever, it nearly jumps out of the leader groove. Still, it sounds nice-pretty quiet...considering the new VM series from Audio-Technica.

    The 78C cartridge performs very well, with one caveat - -It is susceptible to 60Hz magnetic fields. If the turntable that you use does not have such a field beneath it, you should have no problems. However, the Numark tt200 turntable, possibly among others, DOES generate a 60Hz field, resulting in an unacceptable hum. I reduced this hum to an acceptable level (but did not totally eliminate it) by placing two layers of mu metal foil under the turntable.



    ..a very wise purchase. None will ever track like the old Stanton/Pickering models, of course, but their cantilevers could withstand up to 7 grams. I set mine just under the max. weight (4.5-4.75) and it plays fine: very smooth tone, and clearly quieter than the others mentioned. I came across a one-sided 78, circa 1911, and it was actually fun to hear, since I can ACTUALLY HEAR IT, surface noise was minimal. Early 50's Capitols sound GREAT !!!



    This cartridge was recommended to me by ND and I like it. I'm using it with a Denon DP-300F to digitize old 78 children's records in my collection, resampling for speed correction with DartPro MT. Great results!



    Installed a 78c in a separate headshell on hy Lenco L75 vintage turntable . . . . Now I hear the music as it was recorded , , , ,Even my 75 year old Brunswick recordings sound great, need to adjust the speed however, on the Lenco that is not a problem, practically infinite control on speed . . . . .Very satisfied . . .

    Great cartridge priced right! Get passed all the noise sitting on the surface to the parts of the shellac "where no man has ever gone...."



    I bought one of these to digitize a large collection of 78s donated from an estate. It did a fantastic job, playing all the 78s no matter how old or worn. It imparts a warm natural sound, and as drehud says 'brings the music back to life". I was struck wondering if the original owner heard the music as well as I did, 80 years later. If you have 78s to play, this phono cartridge deserves a place in your setup.



    First 78 cart for a DIY tonearm. Sounded great! Clear and lively throughout. Awesome cart!



    Brings my old 78rpm Jazz records to life as if was there with closed eyes...



    I upgraded from a Stanton 500-II with a 78 rpm Mono stylus to the Grado 78c. What a huge difference. The noise of a vintage record is dramatically reduced. Beat records are listenable. Moderately worn records sound good and near mint records sound as good or better than LPs. There is a bit of jumping in the inner grooves with the S shaped tonearm on my so-so Numark TT-1. This is easily remedied by raising the playing surface ever so slightly. I highly recommend this cart. for lovers of pre-LP era records of all kinds. it brings the grooves to life.
