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.\u003c\/p\u003e\n\n\u003ch4\u003eMounting Dimensions and Compatible Tubes\u003cbr\u003e\n\u003c\/h4\u003e\n\n\u003cp\u003eThe mounting hole diameter is 30mm, and the screw spacing is 38.2mm.\u003cbr\u003e\nCompatible vacuum tubes are Magnoval 9-pin base tubes such as WE436A, WE437A, WE418A.\u003c\/p\u003e\n\n\u003cdiv style=\"text-align: start;\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0612\/9139\/7377\/files\/UX_UF_UY_UZ-sunnpouzu_600x600.jpg?v=1722003296\" alt=\"\" style=\"margin-bottom: 16px; float: none;\"\u003e\u003c\/div\u003e\n\n\u003ch4\u003eExcellent Insulation and Stability from Machined Fluororesin\u003cbr\u003e\n\u003c\/h4\u003e\n\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\n\u003cp\u003eFor 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.\u003c\/p\u003e\n\n\u003cp\u003e\u003cimg alt=\"\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0612\/9139\/7377\/files\/IMG_4856_9b340f8a-721d-40ff-896e-553390c2a67b.jpg?v=1766484176\"\u003e\u003c\/p\u003e\n\n\u003ch4\u003eReliable Contact with Gold-Plated Contacts\u003cbr\u003e\n\u003c\/h4\u003e\n\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\n\u003cp\u003eVacuum 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.\u003cbr\u003e\u003c\/p\u003e\n\n\u003cp\u003e\u003cimg alt=\"\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0612\/9139\/7377\/files\/IMG_4851_ac6b6b57-2d35-4aaa-8fe4-2aee088de110.jpg?v=1766484176\"\u003e\u003c\/p\u003e\n\n\u003ch4\u003eIdeal for WE-style vacuum tube amplifier construction and restoration\u003cbr\u003e\n\u003c\/h4\u003e\n\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\n\u003cp\u003eTo 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.
