Fairchild SM1 Cartridge

Fairchild progress is typified in the new SM-1 Rotating Magnet Compatible Stereo/Monophonic cartridge.
The efforts of Fairchild's engineering staff, skilled as no other group in professional transducers, has culminated in a sleek, functionally designed cartridge.
The Fairchild SM-1 will complement any home music system. It is sufficiently rugged to stand the abuse of the most ancient record changer, yet it will enhance the performance of the finest professional arms and turntables.
Its high output permits quiet operation of the most economical of kit amplifiers, while the wide response will test the finest stereo amplifier-preamplifier units on the market.
Comparision of the specifications will convince you that, for stereo cartridges, all you need say is Fairchild.

SPECIFICATIONS
