Pickering Needle Stylus A well-maintained turntable is a marvelous music machine. A stylus under good working conditions has a useful life of about 1,000 playing hours. To ensure that you always have a replacement stylus for your specific cartridge, we recommend that you order two and keep the other as backup. Replacement styli for older models are no longer being produced. So stock up now before they are gone forever. You'll be happy you did.
