A machined aluminium frame supports the cartridge assembly.\u003c\/p\u003e\u003cp\u003eWith 3.0 mV output, it is intended for a moving-magnet phono input—not a low-output moving-coil setting. Nagaoka specifies a 1.3–1.8 g tracking force and 47 kΩ loading. The JN-P500 stylus assembly is replaceable, so the cartridge body can remain in service when the stylus needs renewing.\u003c\/p\u003e","brand":"Nagaoka","offers":[{"title":"Default Title","offer_id":54073701630228,"sku":"MP-500","price":1159.95,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1014\/9058\/9972\/files\/df05cc06445ea1edba3752be2e235795.jpg?v=1790363302","url":"https:\/\/speakerandsong.ca\/products\/nagaoka-mp-500-mp-cartridge","provider":"Speaker \u0026 Song","version":"1.0","type":"link"}
