Stanton M80-ED
Collectors can confirm only what a 1968 mail-order ad said about this cartridge.
Overview
The Stanton M80-ED shows up in period advertising and then disappears into missing documentation. What little is verifiable comes from a single recurring classified ad placed by DEFA Electronics of 2207 Broadway, New York, which ran in Audio during 1968. The ad offered a trade. Send in $19.95 and any old cartridge, and DEFA would ship a new, prepaid, "top rated elliptical diamond stereo cartridge" from a short list of models. The M80-ED is on that list, identified as the M80ED "for Lab 80."
That "for Lab 80" tag is the most concrete thing anyone has on the cartridge. It points to the turntable the M80-ED was apparently meant to fit. The ad's companion entry, the M80ED19, is tagged "for Dual 1019," so Stanton seems to have offered model-specific variants of the same basic cartridge, each tailored to a particular turntable's mounting or stylus geometry. The "ED" suffix conventionally signaled an elliptical diamond stylus in that era, and the ad's own copy describes the whole lineup as elliptical diamond stereo cartridges. But that is inference from a sales listing, not a manufacturer specification, and no Stanton document confirming the M80-ED's technical details has surfaced in the available record.
What the ad does establish is that one New York mail-order house considered the M80-ED a "top rated" elliptical. It shared a list with the Pickering V15AME3, the Empire 888SE, the Shure M55E, and Stanton's own 500E. Those were the workhorse moving-magnet cartridges of the late 1960s, the ones a budget-conscious listener or a small studio would actually buy. The $19.95 trade-in price, with the old cartridge shipped prepaid, was a classic high-volume retail tactic of the period. It suggests the M80-ED was priced as an accessible upgrade rather than a reference-grade instrument.
Beyond that, the honest answer is that the M80-ED is poorly documented. No frequency response, output voltage, tracking force, or impedance figure can be attributed to it from the sources at hand. Collectors who encounter one — usually as a stylus-less body in a box of old cartridges, or still mounted on a Lab 80 turntable — should treat any specification they read online with suspicion unless it is backed by a Stanton data sheet. The cartridge's real significance is as a footnote to the Lab 80 ecosystem and to the mail-order culture that kept affordable ellipticals flowing to hobbyists in the late 1960s. It is a genuine piece of the period, but a mysterious one, and the archive would rather say so than invent a spec sheet for it.
