The original tube socket is made by machining fluororesin and fixing pins in a circular cutting process. This ensures a tight fit, securely holding the vacuum tube and preventing sound quality degradation due to vibration. In addition, the excellent insulation of the fluororesin makes it a key component in building vacuum tube amplifiers.
Explanation of Materials Used:
Fluororesin:Officially called polytetrafluoroethylene, it has the highest electrical insulation and dielectric constant of any solid. It also has excellent temperature resistance.
Phosphor Bronze:Used for the pins of most tube sockets (except L series). It has high strength, excellent spring properties, and maintains stable contact.
Gold Plating:Most socket pins are plated with gold over a non-magnetic base material (except L series). Magnetic materials are minimized in the plating.
