I'm using a P-mount Pickering TL-3 cartridge on my vintage Technics SL-Q200 turntable and I have noticed recently that I'm getting a faint ringing or jingling noise whenever the arm sets onto the record or if there is a slight vibration to the platter. I never had this before. I thought maybe it was the replacement stylus I was using, so I went back and checked using the original DTL-3S stylus and I'm still hearing the same thing. I checked the connection between the cartridge and the tonearm and I don't find anything loose. I know this cartridge is at least 25 years old; has it just outlived its usefulness? Thanks for any help or advice.
