This listing is for qty. 4 original RCA SelectaVision VideoDisc stylus cartridges, stock number 154216. These units are all defective, they were sourced directly from the RCA Special Parts Distributor in Deptford, New Jersey. The cartridges are all brand new old stock in theiroriginal RCA boxes and have never been used or installed (100% defective).
Please note that these (4 pieces) are all factory-defective units. The internal ribbon-like conductor, a thin gold-plated beryllium-copper flexure strip, has become broken/disconnected from the strips on the stylus shaft. Many say this was a design defect. On a correct working stylus cartridge, this ribbon forms a small U-shaped loop and is bonded to the metal shaft to carry the electrical return signal and maintain proper mechanical compliance. With this unit, the ribbon is detached and broken. Please understand you are buying a defective broken unit that does not work. It has a broken connection.
Because of this broken connection, the stylus cartridges cannot function in its current state and are being sold strictly as-is, for parts, study, or restoration purposes.
Some collectors and restorers have reported that this ribbon can potentially be reattached using advanced repair methods. The original factory method was micro spot welding, and the modern hobbyist method uses a very small amount of silver conductive epoxy applied under magnification. These techniques require extreme precision, and positive results cannot be guaranteed. This listing does not guarantee that the cartridge can be repaired or made functional.
