The original tube socket is made of fluorocarbon resin (or Comptonite), and a round machined pin is fixed to the tube socket. The tube is securely held in place without rattling, preventing sound quality deterioration due to vibration. 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.
