Yamamoto Sound Craft 4P tube socket for 316A

Specially designed to fit Western Electric 316A/388A

This product is compatible with 316A and 388A products including Western Electric. output tubeA 4-pin tube socket compatible with The design takes into account the heat generation and mass characteristic of large triodes, and can be used in a wide range of applications, from building new vacuum tube amplifiers to restoring vintage machines.

The mounting hole is 35mmφ, the screw spacing is 45.2mm, and the height on the dimensional drawing is set to 15mm.

Reliable hold and high insulation performance

The socket body is machined and molded from fluororesin (tetrafluoroethylene). This material has extremely high electrical insulation properties, low dielectric constant, and excellent heat resistance properties, making it ideal for vacuum tube amplifiers used in high-voltage, high-temperature environments. The pin is precisely fixed by round cutting, and its secure holding force without wobbling prevents poor contact and sound quality deterioration due to vibration.

Pin structure that creates stable contact

The socket pin uses phosphor bronze, which has excellent strength and spring properties, and maintains stable contact pressure over a long period of time. Furthermore, by applying a thick gold plating on top of a non-magnetic base treatment, contact resistance is reduced and resistance to aging is increased. Another consideration unique to audio applications is the elimination of magnetic materials, which tend to adversely affect sound quality, as much as possible.

Maximize performance by mounting with heat dissipation in mind

Since the 316A and 388A are vacuum tubes that generate a large amount of heat, it is possible to achieve both reliability and sound quality by designing sufficient heat dissipation when using this socket. Due to its robust structure and high-quality material selection, this socket can be used for a long time as an important basic component in the production of vacuum tube amplifiers.
