Specifications

Ortofon has designed and manufactured magnetic cartridges for about 30 years. In providing an economic alternative to the renowned Ortofon moving coil cartridges, the magnetic models have established a firm position for themselves among music lovers and audiophiles all over the world.

Naturally, the magnetic cartridges also benefit from Ortofon's research and experience in transducer technology. Sophisticated styli, light and rigid cantilevers, and advanced magnetic circuitry have produced a level of quality which is state-of-the-art within the magnetic category. The present magnetic range consist of several different lines, covering every possible combination of sound quality, mounting standard, and price.

Your investment in an entry level cartridge from Ortofon's magnetic range never becomes worthless. As your awareness of musical details develops, and your demands to audio equipment increase, it is nice to know that all stylus units for the different lines, are completely interchangeable within their own series.

Lovers of the realistic reproduction of music in the home are discovering in increasing numbers, that the analogue technology of the black vinyl record is still superior to the digital Compact Disc by a comfortable margin.

I paid $48.84 on eBay with shipping and insurance.
