This is a 7P socket used for transmitting tubes like 813 or 4E27.
The original tube socket is made by machining fluororesin and fixing the pins through circular cutting processes. This ensures there is no looseness and securely holds the tube, preventing sound quality degradation caused by vibration. Additionally, the excellent insulation properties of fluororesin make it a key component in vacuum tube amplifier construction.
Materials Used:
Fluororesin:Officially named polytetrafluoroethylene, it has the highest electrical insulation and dielectric constant among all solids and excellent temperature resistance.
Phosphor Bronze:Used for the pins of most tube sockets (excluding the L series). It has high strength, excellent spring properties, and maintains stable contact.
Gold Plating:Most socket pins are coated with a non-magnetic base material followed by thick gold plating (except L series). Magnetic materials are minimized even in the plating.
