19801 📃
A fold-out brochure covering Audio-Technica phono cartridges as of September 1980. The inner spread explains the VM principle: the cartridge body mirrors the shape of a cutting head for accurate groove tracing, with a side-by-side comparison of VM and MC designs. Three families: toroidal VM cartridges AT25/AT24/AT23 at the top, paratroidal AT150E/G through AT120E/G in shells and bare, and MC cartridges AT34/AT32/AT30E/G with the AT34 at ¥38,000 featuring a dual magnet-coil system. A specs table, tonearm AT100, microphone AT813 and accessories close the catalog.
