All info from gradolabs.com, except this: DON'T remove the goo from inside the cartridgewhen you remove the needle. It's some sort of sound dampening stuff; installed by Grado on purpose! Also! this needle is very difficult to replace. Please practice with your old needle 1st a couple times to get the hang of it as it is very easy to slip and break off the cantilever when inserting the new needle. If by some miracle you still have the box from the cartridge there should be a special tool to grab the 'ears' that stick out the side of the cartridge to help pull the needle down and out.

All Grado cartridges now use a derivation of the moving iron principle which feature patented OPTIMIZED TRANSMISSION LINE cantilever technology, PIVOTED FIXED AXIAL STYLUS-GENERATOR MODULE, and Grado's FLUX-BRIDGER GENERATOR SYSTEM.OPTIMIZED TRANSMISSION LINE (OTL) STYLUS/CANTILEVERGrado'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 GradoÕs OTL technology is all about, more performance.PIVOTED FIXED AXIAL CANTILEVER STYLUS-GENERATORThis 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.This proprietary design allows the implementation of the Flux-Bridger Generator System!FLUX-BRIDGER GENERATOR SYSTEMThe 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.
Fewer coil turns allow Grado cartridges to have lower mass and lower electrical inductance, making them insensitive to tone arm cable capacitance. The four gap design is perfectly balanced and eliminates magnetic residue which contributes to increasing distortion over longer time periods. Grado cartridges reduce distortions that cause listeners fatigue.HAND-BUILT IN USA WITH 100% QUALITY CONTROLEach 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.
"DE" =Diamond .3 X .7 mil elliptical (if you get the blue version) tip needle for use at 16, 33 or 45 speeds. NOT for 78 rpm speed. • 1 - 2 grams tracking pressure. • Elliptical needles have more efficient contact with the surface of the record than a conical tip.• Original needle color is usually: Black or Tan • 16 or 33 or 45rpm NOT for 78rpm • Replaces: GRADO F3E-S F3E+S G3E+S G80 etc.• Radio SHACK NEEDLES RS810 RS811 RS812 RS816
