ADC LX-III ()
Finding a new stylus for a 40-year-old cartridge shouldn't feel like a win, but when it clicks into place and the grooves come alive again, it does.
Overview
The ADC LX-III never made headlines. It doesn't show up in glossy brochures or collector roundups, yet it still earns its keep decades later in systems held together by loyalty and solder. According to forum users who have dug into parts compatibility, the LX-III appears to have flown under the radar in its day and never became a staple of ADC's lineup. It was good enough to last, and rare enough that finding a replacement stylus feels like striking gold.
Owners report the satisfaction of resurrecting old gear. One notes they were able to "find a matching stylus to my old ADC LX-III" with no fuss, and that it "fits well and plays fine." Another calls it "great to find a new stylus for a 40 year old cartridge." Nobody is claiming sonic transcendence. The cartridge just keeps working.

Key Features
Stylus Design
The ADC LX-III's stylus is a highly polished special elliptical diamond. It is not a line contact or a Shibata. It's a well-executed elliptical profile, shaped and finished to trace record grooves with precision. The polish isn't just cosmetic. It reduces surface noise and wear, and helps the tip glide through high-frequency modulations without chattering. Retailer descriptions say this design delivers "superb tracking and tracing of record grooves," resulting in "finer detail and harmonically complete sound quality." That's marketing language, but paired with user reports of clean playback and proper fit, it suggests the stylus was engineered for accuracy within its class.
There's no data on tracking force, output, or compliance, so setup relies on experience or educated guesses. Replacement styli still exist and still fit, which says something about the build consistency of the original cartridge. It may not have been cutting-edge, but it was made to standards that allowed long-term serviceability, which is more than you can say for some of its contemporaries.
Collectibility & Value
The ADC LX-III doesn't trade as a complete cartridge on the secondary market, at least not with any consistency or visibility. What is available is the replacement stylus, currently priced at $73.00. That's not cheap for a stylus alone, but it's not surprising given the niche demand. For someone with a working LX-III body from the 1970s or 1980s, that $73 means keeping a familiar sound without hunting for an entire used cartridge of unknown condition. One user put it plainly: "Stylus fits well and plays fine in my vintage 1970's cartridge."
There’s no data on original pricing, production years, or country of manufacture, so the LX-III remains a ghost in the machine—present in parts, absent in history. It’s not a collector’s trophy, but it’s not obsolete either. It occupies a middle ground: a forgotten workhorse that still earns its keep, one re-tipped body at a time.
