high quality teflon socket
Large socket used for triode output tube GM-70
To stably bring out the performance of the large triode GM-70
This product is a large three-pole made in Russia.output tube A 4-pin tube socket compatible with GM-70. Based on the characteristics of the GM-70, which operates at high voltage and high output, it is designed with emphasis on mechanical stability and electrical reliability.output tubeAs a socket, it is an important part that aims to achieve both sound quality and long-term stability.
Installation dimensions and correspondence
The mounting hole diameter is 55mm, and the screw spacing is 48mm x 4. The height (H) in the dimensional drawing is 25mm.
Please note that if you are using a 7-pin type vacuum tube, please contact us in advance as the specifications may differ.
High holding performance and insulation due to fluororesin machined structure
The socket body is machined from fluororesin (tetrafluoroethylene). The precisely machined structure does not wobble and securely holds the large and heavy GM-70. This prevents poor contact and sound quality deterioration due to slight vibrations during operation, supporting stable operation.
Fluoropolymers have extremely high electrical insulation properties and low dielectric constants, suppressing leakage and noise generation even under high voltage conditions. It also has excellent heat resistance and maintains reliable performance even after long periods of use.
Stable contact with phosphor bronze pin and gold plating treatment
The socket pin uses phosphor bronze, which has excellent springiness and strength. It maintains stable contact pressure even when the vacuum tube is repeatedly inserted and removed, and maintains highly reliable electrical contact even after long-term use.
Furthermore, by applying thick gold plating on the non-magnetic base material, oxidation is prevented and changes in contact resistance are suppressed. By eliminating the influence of magnetic materials as much as possible, we support highly transparent playback.
Key parts for amplifier production with an emphasis on reliability
Yamamoto Sound CraftThe 4P tube socket for the GM-70 has been designed with particular attention to material selection and processing precision as a key part that reliably supports the stability and sound quality required for large triode amplifiers.
