Audio-Technica AT33MONO Phonograph Cartridge
Couldn't load pickup availability
The AT33MONO is designed specifically for use with mono vinyl records.* Due to the horizontal configuration of its PCOCC (Pure Copper by Ohno Continuous Casting) voice coils, the AT33MONO cartridge only generates electrical signal with horizontal movement, yet it also has appropriate compliance in the vertical direction, making it safe for use with stereo records. The cartridge’s 0.65 mil conical stylus is mounted on a hard duralumin cantilever for excellent sound reproduction and dependable performance.
Because the AT33MONO does not easily pick up unnecessary strain components from distorted or scratched records, it produces mono audio of a much higher quality than that generated by a stereo cartridge. The cartridge features a strong, rigid body and incorporates Hanenite rubber in the interior and cantilever fulcrum support to eliminate unnecessary vibrations.
* This cartridge with 0.6 mil conical stylus is not compatible with SP (standard play) shellac records. It is designed to play microgroove 33-1/3 and 45 RPM vinyl records.
Please Note: AT33MONO’s stylus assembly is not field-replaceable, but Audio-Technica offers a fee-based Moving Coil Exchange Program to properly service your moving coil cartridge.
