ceramic cartridge การใช้

• Most had ceramic cartridges and diamond styluses ( needles ), with a separate stylus for 78rpm records.
• Most used sapphire pickups housed in ceramic cartridges, and they lacked features of earlier units, such as auto-start and record-stacking.
• In 1994, Price Pfister became the first manufacturer to convert to ceramic cartridges, which enabled the industry s first lifetime guarantee against leaks and drips.
• Because the magnet is small and has little mass, and is not coupled mechanically to the generator ( as in a ceramic cartridge ), a properly adjusted stylus follows the groove more faithfully while requiring less tracking force ( the downward pressure on the stylus ).
• During the 1950s to 1970s, ceramic cartridge became common in low quality phonographs, but better high-fidelity ( or " hi-fi " ) systems used magnetic cartridges, and the availability of low cost magnetic cartridges from the 1970s onwards made ceramic cartridges obsolete for essentially all purposes.

• At the seeming end of the market lifespan of ceramic cartridges, someone accidentally discovered that by terminating a specific ceramic mono cartridge ( the Ronette TX88 ) not with the prescribed 47 k? resistance, but with approx . 10 k?, it could be connected to the moving magnet ( MM ) input too.
• A more complete field solution that includes chemical disinfectants is to first filter the water, using a 0.2 祄 ceramic cartridge pumped filter, followed by treatment with iodine or chlorine, thereby filtering out cryptosporidium, Giardia, and most bacteria, along with the larger viruses, while also using chemical disinfectant to address smaller viruses and bacteria that the filter cannot remove.
