The original tube socket is made by cutting fluoropolymer and fixing the pin by round cutting. This prevents sound quality deterioration by vibration because the vacuum tube is held firmly without rattling. It will also be a key part of vacuum tube amplifier construction due to its excellent insulation properties.
Description of the material used
FluoropolymerThe official name is ethylene tetrafluoride, electrical insulation and dielectricity are the best of all solids. Excellent temperature resistance.
Phosphorus bronze: Most tube sockets (except L series) are used as pins. High strength, excellent spring properties, maintain stable contact.
Gold Plating: Most socket pins are made of non-magnetic base material with thick gold plating. (Except L series) We eliminate magnetic materials as much as possible from plating.
