Yamamoto Sound Craft LoctalBSP 8P Tube Socket

Equipped with a locking mechanismLoctalSocket exclusively for tubes

This product is representative of types such as 7C5, 7N7, 7AF7, 1LA4, 5AZ4, etc.LoctalThis is an 8-pin tube socket corresponding to tubes.LoctalIt supports the tube-specific center pin structure and features a mechanism that securely locks the tube when it is inserted all the way in. This prevents loosening and contact issues during use, ensuring a stable operating environment. The mounting hole diameter is 30mm, and the screw spacing is 38.2mm, allowing it to be easily incorporated into general chassis designs.

High holding power and reliability due to the machined structure.

The socket body is shaped by machining fluororesin and precisely securing the pins through circular cutting. This structure ensures there is no play,LoctalIt securely holds the tube. In combination with the locking mechanism, it suppresses contact fluctuations caused by vibrations and prevents the generation of microphonic noise, which can be a factor in sound quality degradation.

Stable Electrical Characteristics of Highly Insulating Fluororesin Body

The fluororesin (tetrafluoroethylene) used for the body has the highest level of electrical insulation and low dielectric constant among solid materials. It also has excellent heat resistance, maintaining stable electrical characteristics in circuits where high voltage is applied or during long-term operation.LoctalIt serves as a highly reliable basic component in tube-based amplifier construction.

Reliable Contact with Phosphor Bronze Pins and Gold Plating

The socket pins use phosphor bronze, which has excellent strength and spring properties, maintaining stable contact pressure even with long-term use. Additionally, by applying a thick layer of gold plating over a non-magnetic base treatment, contact resistance is reduced and loss of minute signals is suppressed.LoctalSupports high-purity playback without compromising the tube's characteristic smooth and calm tone.
