Yamamoto Sound Craft 4P Tube Socket for 304TL/TH

Specifically designed for large transmitting tubes 304TL and 304TH

This product is a jumbo-size 4P tube socket compatible with large transmitting tubes, such as the 304TL and 304TH. It is designed with a focus on mechanical strength and reliability, assuming the use of vacuum tubes with high heat output and weight.

The mounting hole has a diameter of 55mm, the screw spacing is 48mm x 4, and the height according to the dimensional drawing is 28mm, allowing easy installation even on large chassis.

Secure holding power and high heat resistance/insulation structure

The socket body is molded from machined fluoropolymer (tetrafluoroethylene). This material has very high electrical insulation and low dielectric constant, and its heat resistance makes it ideal for large transmitting tubes operating in high-voltage and high-temperature environments. The round-machined pin fixation structure securely holds the vacuum tube, preventing poor contact due to vibration and deterioration of sound quality.

Pin design supporting stable contact

The socket pins are made of phosphor bronze, which provides excellent strength and springiness, maintaining stable contact pressure over a long period. Additionally, after a non-magnetic base treatment, thick gold plating is applied to reduce contact resistance and suppress performance degradation over time. The design, which minimizes the use of magnetic materials, reflects a philosophy of prioritizing sound purity for audio applications.

Maximizing performance with heat dissipation design

Since the 304TL and 304TH generate a large amount of heat, using this socket with adequate heat dissipation measures allows the vacuum tube to perform reliably. Its robust structure and high-quality material selection make it a reliable key component suitable for long-term use in large transmitting tube amplifier construction.
