Historical Product

TM 30H, TM20H
and TM14

When Technics approached Ortofon in 1980 with the proposal to develop a series of cartridges exclusively for use with their new range of compact turntables, we willingly agreed. The Technics SL turntables, with their special lightweight linear tracking tonearms, represented an entirely new concept in design and technology.
It was a challenge hardly to be resisted.

Ortofon set about developing two entirely new magnetic cartridges that could plug directly into the linear tracking arms of this new generation of turntables. The resulting TM 30 H and TM 14 magnetic cartridges set the seal on the Technics/Ortofon joint venture. Later, two new models was added to this special series of cartridges, designed exclusively for Technics: the TM 20 H magnetic cartridge and the Moving Coil TMC 200.
