Turntable Stylus Needle Accessory For Lp Vinyl Player Phonograph Gramophone Record Player Stylus Needle

​Feature: Polarity: When the needle tip is driven laterally (left+right), the phase of the output voltage of the left channel (1) and the right channel (R) should be the same. Vocal needle: ruby output voltage When the frequency F is 1KHZ, the output voltage relative to the specified value (250M) should be within ± 4DB range (i.e., within the range of 00-300MA) when the acoustic groove vibration velocity V in the L or R direction is 3.54CM/S or the transverse acoustic groove vibration velocity is 5CMS Needle pressure: When testing the tracking ability and electrical parameters of the pickup head, it should be measured within the range of 40+10MN needle pressure. Needle tip life: Ruby=P Wear resistance life is about 120H Specification: Size:28*10*10mm Package including: 1Pc * Stylus Needle Note: There could be some slight differences in the color tone of the pictures and the actual item.
