Audio-Technica AT3
The Audio-Technica AT3 is a phono cartridge with very little documentation. Audio-Technica's own current product pages still list it, and those give the few solid facts there are. No production years, no original price, and no period reviews in the major hi-fi magazines have surfaced.
What is known comes from the manufacturer's specifications. Tracking force range is listed as 1 to 3 grams. A period review in High Fidelity (December 1974, p.53) lists a tracking force of 2.5 g, a weight of 9.5 g, and a 0.6-mil non-replaceable spherical stylus on an aluminum cantilever. Beyond that, stylus type, weight, compliance and recommended load are not documented. It appears to have been a budget-oriented offering, likely from the late 1970s or 1980s, but that's inference, not record.
If you own one and can fill in the blanks - stylus profile, cantilever material, mounting details, or just when you bought it and what it cost - the archive would like to hear from you.
