The original tube socket is made by machining fluororesin (or ) and fixing pins with circular machining. This ensures a secure fit without looseness, preventing sound quality degradation due to vibration. Additionally, the excellent insulation properties of fluororesin make it a key part in building tube amplifiers.CompriteDescription of Materials Used
Fluororesin:
Official name is polytetrafluoroethylene (PTFE), with the highest electrical insulation and dielectric constant among all solids. It also has excellent temperature resistance.Phenolic Resin:

CompriteWood is forcibly dried and impregnated with phenolic resin as a base material. Electrical properties are the same as Bakelite but with higher strength. It also has high heat resistance and strength, resulting in solid sound quality.
Phosphor Bronze:Used as the pin material in most tube sockets (except L series). It offers high strength, excellent springiness, and maintains stable contact.

Gold Plating:Most socket pins are plated with a thick layer of gold over a non-magnetic base material (except L series). Magnetic materials are minimized in the plating.
