Audio-Technica AT-155LC
Not much information on the Audio-Technica AT-155LC survives, but the period record shows it was the top model in a new "Vector Aligned" line of stereo cartridges. HiFI-Stereo (September 1981, p.54) said it used a high-efficiency magnetic structure based on the toroidal-coil design Audio-Technica had introduced a couple of years earlier. Four less expensive models sat below it in the range.
The same review gave a recommended tracking force of 0.8 to 1.6 grams and a recommended load of 47,000 ohms with 100 to 200 picofarads of capacitance. It also noted that the user-replaceable stylus assembly included a hinged stylus guard. Test measurements in the following pages appear to have been made at 1.5 grams tracking force with a 180-pF load shunting 47,000 ohms (p.56). The Archive's file is essentially just this review. No factory documentation or original US price has surfaced.
- Recommended tracking force: 0.8–1.6 g
- Recommended load: 47 kΩ, 100–200 pF
- Replaceable stylus assembly with hinged guard
- Top model in Audio-Technica's "Vector Aligned" cartridge line
