The original tube socket is made of fluorocarbon resin (or COMPLITE), and a round machined pin is fixed to it. This prevents deterioration of sound quality due to vibration, since the tube is held firmly without rattling. The excellent insulating property of fluoroplastic also makes it a key component in the construction of vacuum tube amplifiers.
Explanation of materials used
Fluoroplastic: Official name is ethylene tetrafluoride, which has the highest electrical insulation and dielectric constant of any solid. It also has excellent temperature resistance characteristics.
Phosphor bronze: Used as the material for the pins of most tube sockets (except L series). It has high strength, excellent springiness, and maintains stable contact.
Gold plating: Thick gold plating is applied to most socket pins over a non-magnetic base material. (Except for the L series) Magnetic materials are also eliminated from the plating as much as possible.
