This needle is the ultimate upgrade for any stylus on our website starting with 108,109, 110, 111, or 113
We are very excited to have run across this extremely rare Astrion. We found it listed in the June 1st, 1986 (a great year btw) price list and it sold for $20 more than the widely acclaimed ZLM needle.
for use at 16, 33 or 45 speeds. NOT for 78 rpm speed.
Original needle color is: CLEAR
Replaces: RSA ASTRION
Used in: ASTRION cartridge by ADC
Hand-built Line contact, hand-poished radii Dimensions 0.25 mils scanning radius X 1.50 mils bearing radius Tracking force 1 gram - 1.4 grams (nominally 1.20 grams) Frequency response 20Hz to 20kHz +- 1dB; 20Hz to 26kHz +- 1.50dB Output Output balance Channel separation 30dB at 1kHz; 20dB at 10kHz Inductance Resistance Load resistance 47,000 ohms Load capacitance 275pF Cartridge weight 5.70 grams Notes: Audio Dynamics Corp "top-of-the-line" cartridge. Inducted magnet transducer. Newly developed "Pivot System" which reduces the moving mass of the stylus system. No armatures or adhesives. Precision armature fitted to a compliant suspension block. Stylus cantilever is a laser-etched solid-sapphire rod with a high stiffness-to-mass ratio, minimized flexing and maintains stylus resonance above 25kHz and beyond. Low-frequency resonance (as tested by Stereo Review): 8Hz including tone arm weighting about 26 grams. "The Astrion's combination of high output, virtual independence of output load condition, extreme flatness of frequency response and uniformity of crosstalk response is noteworthy. Together with its low tracking pressure (its special tip shape distributes the already small tracking force over a wider area of the groove wall than the usual elliptical stylus), these factors make it one of today's better cartridges and one of which ADC can justifiably be proud. " - referenced from Stereo Review, January 1982
NOTE: Because this needle is designed for use specifically with ADC cartridges, it can be found in numerous brands of turntables. In some cases the cartridges for this needle may be original equipment supplied with a new turntable, but was more likely selected at time of sale to complete a turntable sold without a cartridge or later as an upgrade to the original cartridge supplied by the turntable manufacturer. This needle should be matched primarily to the cartridge type not necessarily the turntable.
