The original tube socket is composed of fluoroplastic machined and fixed with a round machined pin. This prevents deterioration of sound quality due to vibration, since the tube is held firmly without rattling. The fluoroplastic also has excellent insulation properties, making 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.
