Yamamoto Sound Craft Magnoval 9P Tube Socket

High-quality socket for Western Electric-type 9-pin vacuum tubes

Magnoval 9P is a fluororesin tube socket compatible with Western Electric models such as WE437A, WE418A, and WE436A.
It is designed to securely hold these vacuum tubes, known for their high-performance small signal and amplification capabilities, ensuring stable contact conditions during use.

High-grade vacuum tubes like the WE437A and WE418A are often used in critical positions in amplifiers, preamps, and phono equalizers, where the sound quality is greatly influenced. Therefore, the socket needs high insulation, heat resistance, and contact reliability. This product meets those requirements with a high-quality specification featuring a fluororesin body and gold-plated contacts.

Mounting Dimensions and Compatible Tubes

The mounting hole diameter is 30mm, and the screw spacing is 38.2mm.
Compatible vacuum tubes are Magnoval 9-pin base tubes such as WE436A, WE437A, WE418A.

Excellent Insulation and Stability from Machined Fluororesin

The socket body uses fluororesin, which has excellent electrical insulation and heat resistance. It maintains stable performance inside vacuum tube amplifiers, which are prone to high voltage and high temperature, and helps prevent leaks and unwanted noise.

For high-performance tubes like WE437A and WE418A, the quality of the socket affects the sound clarity, quietness, and operational stability. Fluororesin has a low dielectric constant and minimal electrical loss, making it suitable for circuits handling small signals. It can be used as a reliable basic component in sound-quality-focused amplifier construction or restoration.

Reliable Contact with Gold-Plated Contacts

The contact parts are gold-plated to suppress changes in contact resistance due to oxidation. This keeps stable contact over long-term use and ensures consistent performance from the vacuum tube.

Vacuum tube sockets are an important component that is often overlooked in the signal path. If the contact is unstable, it can not only cause noise, sound dropouts, or operational issues but may also affect the clarity and imaging of the sound. This product, which uses gold-plated contacts, provides reliable contact quality to allow safe use of WE-style vacuum tubes.

Ideal for WE-style vacuum tube amplifier construction and restoration

The Magnoval 9P is a tube socket suitable for constructing amplifiers that use 9-pin Western Electric-style vacuum tubes such as the WE436A, WE437A, and WE418A, as well as for restoring vintage equipment.

To use expensive and rare WE-style vacuum tubes with confidence, the quality of the socket supporting the tube is as important as the tube itself. With its fluororesin body and gold-plated contacts, it offers high insulation, heat resistance, and reliable contact, enabling the stable extraction of the tube’s original performance.
