ADC RQLM30 (–)
That click when the needle drops. This little diamond is the part that makes it happen.
Overview
The ADC RQLM30 is a replacement stylus. It is not a full cartridge. It is the business end, the part that rides the groove, and when it wears out the music goes dull and thin. A worn tip also starts damaging your records. If you still play records with an older ADC cartridge, finding the right stylus is a bit like archaeology.
This particular model, also listed as the RQLM-30 or RQLM 30, pops up in the ecosystem of vintage ADC gear as a service part, not a headline product. But don’t let that fool you. It’s built to fit a whole family of ADC cartridges — replacements show compatibility with the RSQ30, K8, RSQ31, RSQ32, RSQ33, RQ30, RK5E, RP32, RSQ34, RQLM36, RSQ36, RQ36, QLM33mkIII, QLM34, QLM34mkIII, K5E, P32, Q36, and QLM36mkII — which tells you something: ADC wasn’t making one-offs. They had a system, and the RQLM30 was a working cog in that machine. Whether you inherited a turntable from the '70s or rebuilt one from eBay scraps, tracking down the right stylus is half the battle. And when you do, you want it to sound honest.
According to LP Gear, a supplier of replacement parts, the current version (sold as model ADC180) delivers a “very good rendition of voice and music.” It's also said to have a “long playing life,” which is the point of a diamond tip. The tip is conical and highly polished. That suggests a focus on consistency and reduced groove wear over time. It isn't exotic.

Collectibility & Value
There's no data on original pricing or production years, and no market for NOS (new old stock) units has been documented. A current replacement version, sold by LP Gear as model ADC180, lists for $40.94. There's no information on common failures or maintenance specific to the original RQLM30. Given its role, the main concern is wear. A worn tip will misread grooves, increase surface noise, and eventually chew up your records. Owners typically replace it based on hours played or audible degradation, not because it breaks.
